Answer 2

Answer and Explanation:

The process of color subtraction is a useful means of predicting the ultimate color appearance of an object if the color of the incident light and the pigments are known. By using the complementary color scheme, the colors of light that will be absorbed by a given material can be determined.

The rules of colour subtraction are as follows:

i) Red colour absorbs Green and blue and reflect red colour  

ii) Blue colour absorbs green and red and reflect blue colour  

iii) Green colour absorbs red and blue and reflect green colour  

iv) Cyan colour absorbs red and reflect blue green (Cyan) colour  

v) magenta colour absorbs green and reflect red + blue ( magenta) light

vi) yellow colour absorbs blue and reflect red green (yellow) light  

vii) black colour absorbs all colours and reflect no light.
