Additive Theory of Light

Primary LIGHT colours are red, green, and blue

SECONDARY light colours are created by combining only two of the three primary colours of light in equal parts

subtractive theory of light
Subtractive Theory of Light

A pigment is a chemical that absorbs some colours of light and reflects other colours of light

The primary subtractive colours are yellow, magenta, and cyan

The secondary subtractive colours are red, green, blue

how subtractive colours reflect light
How subtractive colours reflect light
  • We see the colour yellow because blue light is absorbed and green and red produce yellow
