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"... gordon letwin
