  • These are definitely violet, with a good dose of UV thrown in, and not the “purple” you get from a red-blue combination such as with RGB LEDs. I tested a few of these on a breadboard with 5v and a potentiometer, with a few other lights for comparison. At very low intensities these LEDs appear violet to the eye. As the intensity increases with higher current, the color turns pale blue, and does a pretty good job of lighting up various colors of fluorescent paper, which is the UV portion doing its job. See Wikipedia’s color swatches for blue, violet and purple for comparison.

No public wish lists :(
