[SML] Moving Light Colour Mixing philosophy question

[Riter, Andrew]

Thank you all.  Interesting.  This could be a good discussion.


I like Jerry's point of white source = all colours / RGB = spiky RBG versions of a colour, so subtractive is better colour.  But subtractive is also less intensity in the saturated colours.

The question is more:  why are subtractive systems  CYM and not RGB?

I found that it helped to think of CMY as RGB turned upside-down, in terms of what sliders do.

For why CMY is still there, if it's a profile unit that needs beam consistency all the way through complex optics, RGB(AW) chips would probably get weirdly patchy by the time the light hit a target.  Some "par" units do that too, and need some strategically-placed frost to even out the wash a bit more.  I guess nobody's yet making a multi-color COB emitter?  Possibly more efficient too, but I haven't researched the LPW of those vs. typical multi-chip emitters.
