What kind of set of colors is called when it's dark but has light sensitivity to change?
I'm sure it's used in paints (not cheap either...) has a dark color (indigo, black, dark blue, ect.) but changes when it's illuminated? Like if a plastic was painted with this kind of.. thing so to speak, it reveals and changes to rainbow like colors (not the whole rainbow) but blue, purple, red, light gray, or another color appear when light hits it. What is this kind of paint style called or any coloring tool used for that matter?
Sorry if I placed this in the wrong category, I'm kinda confused where to put this actually...
To Mark1945f: I'm really impressed with your answer :) I may give you the best answer.. however, as strange as it seems I've seen this even work on hair dyes (shocker...) which is why I feel that this specific 'optic of coloration' word puzzle is leaving me unsolved. I always thought it might be 'pearlescent' or something alike that word with the following light effects. Ehh, it's really biting my tongue, I hope you may get back to this answer because I really appreciate your help so far.

As good a place as any.
What you are talking about is not a paint, it is a thin layer of metallic salts and it is applied in a vacuum chamber. It is called dichroic as described here http://en.wikipedia.org/wiki/Dichroism and the black is normally the base material for contrast. It is done on plastic or glass most commonly and pieces of the treated stuff are applied/fused/glued elsewhere.
