I have two of these - in the clear and the diffused package.  I agree that
they're not a deep "violet blue" but I wouldn't describe them as "powder
blue".  Powder blue has a lot of white in it, I think, whereas these
leds don't, obvuiously.  Their peak emission is 470 NM, as I recall,
so those with the right chart can determine the colour.  I'm perfectly
satisfied with the blue - it's a "real, true blue", but it's not a super
dark "royal blue"...
