Information about color is not separable from intensity
What is the result of normalizing the maximum intensity in the RGB color channels to 1?
The RGB color cube
What is the relationship between the wavelengths λ1, λ2, and λ3 in the RGB color model?
They are the wavelengths of the base colors for red, green, and blue
What is the purpose of the CMY[K] color model?
To mix color pigments for printing
