Quaternary colours

A mixture of two tertiary colors gives a quaternary. The quater­nary colors are green, purple, and orange, much neutralized. They are sometimes spoken of as olive, prune, and buff. Quaternary green is a mixture of the tertiaries yellow and blue. Tertiary yellow (B + Y + Y + R) added to tertiary blue (R + B + B + Y) gives this sum of colors-three parts of yellow, three parts of blue, and two parts of red. The result of the mixture is green, from the pre­dominance of yellow and blue, and it is much dulled with the red. The quaternary purple is 'a mixture of the tertiaries blue and red. R + B + B + Y and Y + R + R + B make three parts of red and three parts of blue, giving purple, with two parts of yellow to dull it. Quaternary orange is tertiary red (Y + R + R + B) mixed with tertiary yellow (B + Y + Y + R). This makes three parts of yel­low and three parts of red, which give orange and the two parts of blue neutralize the orange. (Refer Table: 3)
