The present invention relates to a paint set for teaching materials used, of course, in curricula for compulsory education, as well as in education curricula in high schools and more specifically to a paint set comprising paint vessels for respective colors, the paint vessels being circularly arranged to constitute a hue circle.
In lesson processes of art in junior high schools and the like, color education is carried out in which pupils or students experience creative endeavors through the production of works such as paintings and designs, or understand three attributes (hue, brightness, and chroma) of colors, and hue circles. Education on colors, for example, in art classes intended for first-year junior high-school students offers an understanding of three attributes of colors, hue circles, complementary colors, color mixtures, contrast of colors, impressions of colors and the like and offers an understanding of a color change by replacement with a two-dimensional or three-dimensional space, and, thereafter, experiential learning is carried out about colors through the production of works.
The effect (purpose) of learning about three attributes of colors and hue circles includes i) that properties inherently possessed by colors that are uninterruptedly circulated can be visually (intuitively) understood and a color change can be spatially recognized, ii) that a color produced by mixing two colors can be estimated before paints are actually mixed together, and iii) that, regarding a complementary color relationship and contract of colors can be spatially recognized by a positional relationship between colors. In art classes, a teaching method is adopted in which understanding by pupils or students is improved using materials for color education, for example, Munsell hue circles and hue circles of Japanese Practical Color Co-ordinate System (hereinafter referred to also as “PCCS”).
In the production of works such as paintings and designs, a paint set comprising paints of several to more than ten colors is usually used. Pupils or students select a plurality of color paints, and these color paints are mixed together on a palette to prepare a desired color before paintings are produced. A commonly used paint set comprises cylindrical tubes filled with respective paints that are arranged side by side so that similar colors are located adjacent to each other. Pupils or students select or mix colors based on color information (color label or color name) indicated on the surface of the tube.
Such paint vessels include those in which a paint is filled into a conventional tin vessel or a recent cylindrical tube of an aluminum-laminated film. In recent years, paint vessels comprising a paint filled into a resin vessel formed by blow molding have been proposed (Japanese Patent Application Laid-Open Nos. 230907/1996 and 250085/2004). Further, for example, a paint case in which paints of various colors are juxtaposed and housed (Japanese Patent Application Laid-Open No. 86100/1997). Furthermore, teaching aids that can allow a change in hue or a change in brightness and chroma by mixing colors to be learned without the necessity for pupils or students to use paints have been proposed as materials for color education (Japanese Patent Application Laid-Open No. 183392/2007).
In producing works using paints, however, it is necessary to mix a plurality of color paints to prepare a desired color. For pupils or students who do not experience satisfactory learning of colors or pupils or students who do not have satisfactory understanding about three attributes of colors, hue circles, complementary colors, color mixing, and contrast of colors, difficulties are encountered in predicting paints of colors that are to be selected from a paint set and then mixed together to prepare a desired color. This necessitates selecting and mixing of actual paints to confirm whether or not a desired color can be obtained.
Further, paints can be mixed for color mixing using examples from hue circles described, for example, in textbooks. The production of works using examples from textbooks and the like is not practical and poses a problem that it is impossible to focus attention on the production of works. A method can be also adopted in which a small hue circle sample is placed on a pallet or within a paint set and paints are mixed for color mixing using the hue circle. In this method, however, the paint set and the hue circle sample (instrument) should be purchased separately from each other. Accordingly, a troublesome task is required for the provision of them, and a problem of cost also occurs.
Furthermore, in conventional teaching aids and teaching materials for hue circles, regardless of a text type or a suspension type, each color is directly printed, or a print is applied and fixed. Accordingly, each color cannot be moved. As a result, it is impossible to place colors adjacent to each other or to mix colors together.
The present inventors have now found that the provision of a paint set comprising paint vessels of respective colors circularly arranged so as to correspond to a hue circle can solve the above problems. The present invention has been made based on such finding.
Accordingly, an object of the present invention is to provide a paint set that can allow even pupils or students, who do not have satisfactory learning of colors, and even pupils or students, who have unsatisfactory learning experience or knowledge, for example, about three attributes of colors, hue circles, complementary colors, color mixtures and contrast of colors, to easily perform selection and color mixing or color arrangement of desired colors and, at the same time, can allow a learning effect on three attributes of colors and hue circles to be obtained during the production of works.
The paint set according to the present invention comprises a plurality, of paint vessels respectively filled with chromatic color paints each having a hue, the paint vessels being arranged circularly in a storage case to constitute a hue circle.
In a preferred embodiment of the present invention, the hue circle is a hue circle of a Munsell color system or a hue circle of the Chamber of Commerce & Industry Color Coordination Chart (CCIC) color system, a hue circle of a natural color system (NCS), or an Ostwald hue circle.
In another preferred embodiment of the present invention, the hue circle is a hue circle of a practical color co-ordinate system (PCCS).
In a preferred embodiment of the present invention, the number of colors of the plurality of chromatic color paints is 10, 12, 20, or 24.
In a preferred embodiment of the present invention, paint vessels respectively filled with chromatic color paints are tightly arranged adjacent to each other.
In a preferred embodiment of the present invention, the vessels each comprise a lid and a vessel body and has been filled with a paint and the vessel body comprises a pair of surfaces formed in a wedge shape from the upper part of an opening engaged with the lid toward the bottom and a pair of rectangular side surfaces that connect the wedge-shaped surfaces.
In a preferred embodiment of the present invention, the chromatic color paint vessels are arranged so that one of the pair of wedge-shaped surfaces in the vessel body faces upward relative to the storage case.
In a preferred embodiment of the present invention, the chromatic color paint vessels are arranged so that the lid faces outward in the circle.
In a preferred embodiment of the present invention, the vessels each comprise a lid and a vessel body and has been filled with a paint and the vessel body comprises a pair of surfaces in a trapezoidal shape widen from the upper part of an opening engaged with the lid toward the end and a pair of wedge-shaped side surfaces that is formed from the upper part of the opening toward the bottom and connects the trapezoidal surfaces.
In a preferred embodiment of the present invention, the chromatic color paint vessels are arranged so that one of the pair of trapezoidal surfaces in the vessel body faces upward relative to the storage case.
In a preferred embodiment of the present invention, the chromatic color paint vessels are arranged so that the lid faces inward in the circle.
In a preferred embodiment of the present invention, the chromatic color paint vessels are arranged in the storage case so that the surface, in the vessel body, that faces upward relative to the storage case is flat.
In a preferred embodiment of the present invention, the vessel body is formed of a transparent or semi-transparent resin and the hue of the paint filled into the vessel can be perceived through the appearance of the vessel body.
In a preferred embodiment of the present invention, the paint set further comprises a paint vessel that is filled with an achromatic paint and is provided at a position different from the position of the paint vessels filled with the chromatic color paints. In a more preferred embodiment of the present invention, the color of the achromatic paint is white and/or black.
According to another aspect of the present invention, there is provided a paint set characterized by comprising a plurality of paint vessels respectively filled with chromatic color paints each having a hue, the plurality of paint vessels being circularly arranged to constitute a hue circle.
The paint set according to the present invention comprises a plurality of paint vessels respectively filled with chromatic color paints, the paint vessels being arranged circularly in a storage case to constitute a hue circle and thus can allow even pupils or students, who do not have satisfactory learning of colors, and even pupils or students, who have unsatisfactory learning experience or knowledge, for example, about three attributes of colors, hue circles, complementary colors, color mixtures and contrast of colors, to easily perform selection and color mixing or color arrangement of desired colors and, at the same time, can allow a learning effect on three attributes of colors and hue circles to be obtained during the production of works.
According to the paint set of the present invention, paint vessels for respective colors can be taken out separately from each other and can be moved. Accordingly, the paint set of the present invention can fully make up for the problems involved in conventional teaching aids and teaching materials for hue circles, can compare colors on hue circles and can simply simulate the intensity of contrast between colors and can realize very specific and practical color learning effect through the use of actual colors (paints) per se.
According to the present invention, the paint set can also function as a learning material for colors that can allow colors to be gradually spatially perceived by simply possessing or using the paint set.
The paint set according to the present invention will be described with reference to the accompanying drawings. As shown in
Hue circles include a hue circle of a Munsell color system or a hue circle of the Chamber of Commerce & Industry Color Coordination Chart (CCIC) color system in which colors located at opposed positions on the hue circle are in a physically complementary color relationship; or a hue circle of a practical color co-ordinate system (PCCS), a hue circle of a natural color system (NCS), or an Ostwald hue circle in which colors located at opposed positions on the hue circle are in a psychologically complementary color relationship.
For example, when chromatic color paint vessels are arranged so as to constitute a hue circle of a Munsell color system which is a hue circle comprising colors arranged so that opposed positions on the circle are in a physical complementary color relationship, the paint vessels may be arranged so that, according to notation of a Munsell color system specified in JIS Z 8721, basic colors and complementary colors thereof are nR-nBG, nYR-nB, nY-mPB, nGY-nP, and nG-nRP wherein n is an actual number, and colors constituting each of the combinations are located opposite to each other on the circle. Specifically, when chromatic color paints of 10 colors are used, five basic colors (R, YR, Y, GY, and G) are arranged respectively in five equal divided parts of a circle, and complementary colors (BG, B, PB, P, and RP) of the basic colors are arranged at positions opposite to the respective basic colors. The number of chromatic color paints is not particularly limited, but it is common practice to constitute the paint by 10 colors or 20 colors.
When chromatic color paint vessels are arranged so as to constitute a hue circle of a PCCS color system that is a hue circle comprising colors arranged so that the opposed positions on the circle are in a psychological color relationship, a method may also be adopted in which each hue of the PCCS color system is converted to a notation method for Munsell system (JIS standards) and, as described above, the chromatic color paint vessels may be arranged so that the colors constituting each combination of a basic color and a complementary color are located opposite to each other. Further, as shown in
Specifically, when chromatic color paints of 12 colors are used, paints of four psychological primary colors (4R, 5Y, 3G, and 3PB in a Munsell color system) are circularly arranged as basic colors and paints of four psychological complementary colors (5BG, 9PB, 6RP, and 8YR in a Munsell color system) of the basic colors are arranged at positions opposite to the basic colors. Further, in order that the spacing between hues is perceptually moved at a uniform walking rate, a paint of 10R is placed between paints of 4R and 8YR; a paint of 3GY is placed between paints of 5Y and 3G; a paint of 5B is placed between paints of 5BG and 3PB; and a paint of 7P is placed between paints of 9PB and 6RP. In a commercially available paint set, when paints including all colors of four psychological primary colors and psychological complementary colors thereof are not provided, that is, some paints are not provided, it is difficult to circularly arrange the paint set, making it difficult to obtain the same form as the PCCS hue circle.
In the present invention, as shown in
As shown in
In another embodiment of the present invention, paint vessels in which adjacent paints are arranged without space may be as shown in
As shown in
When color labels for color indication are applied on the paint vessels, preferably, color labels are applied onto at least two or more surfaces of each of the vessels. More preferably, the label is applied onto two continuous surfaces. When the color label is applied to two or more surfaces of each of the vessels, the paints per se can be utilized as three-dimensional color samples. Specifically, shade and shadow occur depending upon how the paint vessels are irradiated with light. When the color label is applied onto two or more surfaces of each of the vessels, the difference in brightness between the surfaces can be specifically recognized and, thus, the brightness of colors can be regulated while observing the vessels. Therefore, in the production of works, color arrangement plan and study works can be carried out in a more rapid, intuitively and efficient manner.
In the present invention, preferably, the paint vessel body is formed of a transparent or semi-transparent resin and the color of the paint to be filled into the paint vessel can be recognized through an appearance of the paint vessel. When the transparent or semi-transparent vessel body is used, the color of the paint filled into the vessel can be grasped through the appearance of the paint vessel. Accordingly, the color of the actual paint can be more accurately grasped without relying upon color labels. The paints per se can also be utilized as the color label. Since the color of the paint can be grasped through the whole surface of the vessel, a superior effect as a three-dimensional color sample can be attained. Further, in the paint vessel as shown in
The paint set according to the present invention may further comprise a paint vessel filled with an achromatic paint. Achromatic paints include white and/or black paints. More preferred are white and black paints. The addition of white and black achromatic paints can realize a wide variety of color mixing while taking into consideration a change in brightness and a change in chroma. When these achromatic paint vessels 8, 8′ are arranged in a storage case 9, as shown in
Various embodiments of the present invention have been described. However it should be noted that these embodiments are illustrative only and are not intended to limit the scope of the invention. Further, it is apparent to a person having ordinary skill in the art that various modifications and alterations are possible based on the embodiments. Accordingly, it is intended that all alterations and modifications fall within the scope of the invention.
