Yep! I have tried the other two variations of this (i.e. (violet + yellow + yellow + violet) and (green + red + red + green) ), and this one definitely gives the best result of the three. In normal gameplay, I can't see the blue in the combo I recommeded above, whereas the over-yellow and over-red ones are quite obvious on all the devices I've played with. The blue-black just looks better to the human eye, I suppose. I know one can make a blacker black, but this one is adequate (for me) without being too time consuming.

I think the color is simply derived from the subtractive color mixture of the RYB glowbes. The equal portions of the three basic colors make a true black, with the extra bit of blue tinging it slightly that way. I kind of wish they had gone with an additive system, since we are dealing with little lightbulb creatures here. :)
