Blue Coin Reject Buttons on a Coindoor, Possible?

It wouldn't help for their color when off, but I would bet you could light the reject buttons with blue LEDs and have a pretty good result. I've got a yellow reject button lit with red LEDs and you can't tell they are not red buttons when lit.

Red + ??? = Blue

Yeah, I get it, but my point was that the color of the LEDs so overpowers the color of the buttons themselves that it might work. As always YMMV.

bkenobi:

Ahhh, so you are saying that the filter (translucent coin reject button) will not significantly affect the LED's color.  So by putting a blue LED in there, you will get a blue (maybe slightly violet) light when viewed.

Yellow + Green = Blue.   ;)
