Abstract

A color chart includes three or more concentric circles having three, six, twelve or more color areas. The second circle includes three areas aligned with and designated by that of the first circle and further includes three areas located between and formed by the three colors of the first circle. The third circle includes six areas of the second circle and further includes six areas located between and formed by the six areas of the second circle. A center includes a black triangle and a white triangle each having three angles directed to three basic colors respectively.

Claims

1. A color chart comprising:

at least three concentric circles including a first circle, a second circle, and a third circle having a radius increased from that of said first circle to that of said third circle,

said first circle consisting of three areas designated by yellow (Y), magenta (M) and cyan (C) respectively,

said second circle consisting of six areas, and said third circle consisting of twelve areas, said second circle and said third circle each including three areas aligned with and designated by yellow (Y), magenta (M), and cyan (C), said second circle further including an area located between and formed by yellow (Y) and magenta (M) and designated by red (R), an area purple (P) located between and formed by magenta (M) and cyan (C), and an area green (G) located between and formed by cyan (C) and yellow (Y),

said third circle including three areas aligned with and designated by red (R), purple (P) and green (G) respectively for allowing said third circle to have six areas designated by six colors determined in said second circle, said third circle further including an area orange (O) located between and formed by yellow (Y) and red (R), an area vermilion (V) located between and formed by red (R) and magenta (M), an area eggplant (E) located between and formed by magenta (M) and purple (P), an area blue (B) located between and formed by purple (P) and cyan (C), an area jade (J) located between and formed by cyan (C) and green (G), and an area herbaceous (H) located between and formed by green (G) and yellow (Y).

2. A color chart according to claim 1 further comprising a fourth circle including a radius greater than that of said third circle, said fourth circle consisting of twenty-four areas, said fourth circle including twelve areas aligned with and designated by the twelve colors of said third circle, the twelve colors including yellow (Y), orange (O), red (R), vermilion (V), magenta (M), eggplant (E), purple (P), blue (B), cyan (C), jade (J), green (G), and herbaceous (H) respectively, said fourth circle further including an area orange yellow (OY) located between and formed by yellow (Y) and orange (O), an area orange red (OR) located between and formed by orange (O) and red (R), an area vermilion red (VR) located between and formed by red (R) and vermilion (V), an area vermilion magenta (VM) located between and formed by vermilion (V) and magenta (M), an area eggplant magenta (EM) located between and formed by magenta (M) and eggplant (E), an area eggplant purple (EP) located between and formed by eggplant (E) and purple (P), an area blue purple (BP) located between and formed by purple (P) and blue (B), an area blue cyan (BC) located between and formed by blue (B) and cyan (C), an area jade cyan (JC) located between and formed by cyan (C) and jade (J), an area jade green (JG) located between and formed by jade (J) and green (G), an area herbaceous green (HG) located between and formed by green (G) and herbaceous (H), and an area herbaceous yellow (HY) located between and formed by herbaceous (H) and yellow (Y).

3. A color chart according to claim 1, wherein said at least three concentric circles include a center, said center includes a black triangle having three angles directed to yellow (Y), magenta (M) and cyan (C) respectively, for indicating that a black color is formed when yellow (Y), magenta (M) and cyan (C) are mixed together.

4. A color chart according to claim 1, wherein said at least three concentric circles include a center, said center includes a white triangle having three angles directed to red (R), purple (P) and green (G) respectively, for indicating that a light color is formed when red (R) color light, purple (P) color light and green (G) color light are mixed together.
