I'll try this again at some point, as photographing LEDs is usually an exercise in frustration, but here's a rough idea of how these LEDs compare. I'd mostly pay attention to the glow halos around the LED bulbs.
The first is "pink" vs. the standard "purple" (You can also buy UV Purple LEDs, those are even more blue toned):
And these are: "Sky Blue", my previously owned turquoise ("Ice blue"), and my previously owned "Cyan" (more like jade):
Sky Blue / Cyan / Ice Blue:
Sky Blue / Ice Blue / Cyan:
To put this in perspective, Ice Blue already looks very cyan-green when installed in large numbers on a keyboard. So in that respect, Cyan looks a cold shade of VERY green, and I anticipate Sky Blue to look more green than what I currently have on my keyboards and call "turquoise". I was hoping Sky Blue would be less green than my Ice Blue, but it seems to go the other way around. Still a very nice color to experiment with. The Pink LEDs will go great with purple anodized plates and cases, as the normal Purple LEDs are usually too cold toned to match.
