What is the difference between colors of light and paints ?

Why do mixing of colors yields an entirely different color?

What are pigments ?

What are subtractive colors

Special section in explanatory notes on

--- pigments in nature

additive and subtractive colors

A color pigment or paint absorbs light

A pigment absorbs certain wavelength of colors from white light and emits only definite colors
filter is different from pigment
Mixing of pigments or paints gives different colors than when same colored lights are mixed, this is the key difference between additive and subtractive colors
A filter alsorbs certain colors to pass only a particular color
Details of the animation/ movie /software

The color of an object depends upon which component of light it absorbs, reflects or transmits. For example, a rose appears red because it absorbs all the colors of white light excepts red. As red is the only color reflected by the rose, therefore it appears red.

Objects owe their colors to the presence of pigments. Pigments are optically active substances which absorbs most of the colors of white light but selectively reflects one or more colors. Pigment is a coloring material of mineral, animal, vegetable or synthetic origin. Pigments have no color of their own, but get activated when exposed to white light

Pigment colors combine by subtractive process in which some color is absorbed before mixing of the remaining colors. Cyan, Yellow and Magenta form Primary pigments. In nature no pigment is pure. That means pigments do not absorb all the light colors incident on them. When two pigments are mixed together then the colors reflected by one pigment are absorbed by other pigment and vice-versa, except a common color, which is reflected by both the pigments.

Colored filters are used to obtain light of a specific color. A transparent object, made up of gelatin or glass, which allows a light of certain color (wavelength) to pass through it and absorbs all the other colors (wavelength) of white light is called a colored filter.
