Now add colored ligth to the equation and the surface's color and you get a big old mess.
For instance, if you look at a burgundy colored shirt under typical fluorescent lighting it will look brown because the light hitting the shirt if high in green light and deficient in magenta. Without magenta light hitting the objecgt it can't reflect magenta light and so looks brown.
