Mixing primary blue and primary green light creates a secondary color: cyan light.
Mixing primary green and primary red light creates a secondary color: amber light.
Mixing primary red and primary blue light creates a secondary color: magenta light.
Additively mixing magenta and cyan.
Cyan and amber mixing together.
Additively mixing magenta and amber.
A monochromatic pink/ magenta composition when clear tungsten light is added.
Here the front light is corrected by a slightly pink filter that allows the viewer's eye to perceive it as white light.
Adding a clear tungsten source to a monochromatic blue composition will shift the clear source toward yellow.
This same composition has been corrected by the addition of a pale blue filter that once again allows the eye to perceive the clear source as white light.
In the areas of the figure's T-shirt where the blue and yellow light are both present, watch how the yellow light increasingly desaturates the blue, making it less blue and more white.
As the yellow light increases in intensity it dominates the recessive blue light, overtaking it and turning the figure's T-shirt yellow.
As the yellow sidelight fades up and hits the front of the figure, it completely takes over the blue light.
Here, the same colors are used, but rearranged in the composition so that the yellow (dominant color) light is the backlight and the blue light is coming from the side. This arrangement allows for more places on the figure where only the blue light, which is recessive, appears and results in a more three-dimensionally rendered figure.
