There are three types of color sensitive cells in our retina: red
sensitive, green sensitive and blue sensitive. These cells are called
cones, and their sensitivities correspond to the colors of three
additive primaries Red, Green and Blue.
Additive color mixing works for mixing lights. The rules shown below
apply to stage lights, computer monitors, projectors, and disco lights.
These rules do not apply to
mixing paints or pigments.
The tree additive primary colors are:
In this
computer based physics, you can change the intensity of the additive
primary colors to get all the possible color hues.
When you mix the three additive primary colors in the same amount, you get the white color.
When you mix two of the additive primary colors, you
get an additive secondary color.
