Description: The color of objects depends on the incident light. Here, a poster with colored balloons is lit successively, or at the same time, by original monochromatic primaries red, green, blue.
Addive color model: or additive mixing. The perceived color can be predicted with this model by summing the numeric representations of the component colors.
Subtractive color or subtractive color mixing: Subtractive color or subtractive color mixing give color of objects after light passes through successive layers of partially absorbing media. This model is the principle of how dyes and inks are used in color printing and photography.
