Theories of Color



Additive Theory (Based on Electronic Color)

Subtractive Theory (Based on Pigment Color)

Additive Theory  

The Additive, or light theory deals with radiated and filtered light.

·        Black radiates no light

·        White (sun) radiates all light

Video is the process of capturing and radiating light, therefore it uses Additive (Light) theory not Subtractive (Pigment) theory.

The primary colors in Additive theory are:

–Red ( R )
–Green ( G )
–Blue ( B )

The primary colors add together to make white

Light Theory is also called Additive Theory.

Light Theory is used in Television, theater lighting, computer monitors, and video production.




Subtractive Theory 

The subtractive, or pigment theory deals with how white light is absorbed and reflected off of colored surfaces. A subtractive color model explains the mixing of paints, dyes, inks, and natural colorants to create a full range of colors, each caused by subtracting (that is, absorbing) some wavelengths of light and reflecting the others.

Black absorbs most light

White reflects most light

Colored Pigments absorb light and reflect only the frequency of the pigment color.

All colors other than the pigment colors are absorbed so this is called subtractive color theory. 

Subtractive or Pigment Theory is used in printing and painting. 

The primary colors in Subtractive Theory are:
–Cyan ( C )
–Magenta ( M )
–Yellow ( Y )
–Black ( K )
