[sdiy] Odp: Coloured LEDs

[rsdio at audiobanshee.com]

I'm a bit disappointed that the Optosupply table for OS*4L3131A products does not show the dominant wavelength in nanometers for any of these. Then again, they might all have multiple wavelengths simultaneously. Do you know whether they're pure, single-frequency colors or mixtures?
