It was a wall with small scattered lights in different colors, so they used recessed LEDs. Fine. But instead of color LEDs with a neutral diffuser, it had red+green+blue triple LEDs to make white light, with a red/green/blue plastic in front to recolor it!
I understand how this could be cheaper to assemble or maintain, but I'll never not balk at a system that has components undoing each other's work. Feels almost disrepectful to the technology.
