Saturated Hues and RGB Color Space in Maya
Here's a pure yellow ball sitting on a white table in Maya. Since the table is white, it takes on the color of the light shining upon it, so in this image, the light is also white.
Here's a question for you: What would happen to the yellow ball if I change the light color to pure blue?
Depending on what you think happens to colored objects under colored light you might guess that the ball would become green. You might also guess that the ball would become white.
You probably would not guess that the ball would become black, but that's exactly what happens. Maya multiplies the light color by the object's diffuse color. (1 1 0) times (0 0 1) equals (0 0 0).
If you desaturate the blue light so that there is some green in it - then you will get a nice green ball.
It's very hard to light highly saturated objects.
It's very hard to light with highly saturated light.
In the real world, colors are usually not so pure.
