[SML] Blue LEDs that don't make thing fluoresce?

[*Hobbit*]

Even R80 brought about some amount of that effect, but with a weirdly deep
red component on some dark fabrics [possibly from all the infrared/deep-red
leaking through too].  But typical LED-blue, yeah, freaky.  Adding a bit of
white, if the device has it, or green, seems to even things out fairly well.
"Ice princess" cold cyan-ish-blue is one of my favorite blends.
