That is based on the color of the illumination and this of course affects the perceived color. It's the difference between emitted and reflected light, but in the case of a comparison with musical notes it would be fair to only use emitted light.
There is no exact equivalent to reflected light with its own color illuminating a colored drawing. Though it would be interesting to see if such a thing could be constructed somehow artificially using a device that receives sounds and then somehow frequency shifts them before emitting them again. That would be a fun experiment!
