Bi-color red/green LEDs

[Joel Koltner]

Is it just me, or do most red/green bi-color LEDs seem to have the "red" set
at a wavelength that's really more of an orange than a nice, deep, saturated
red?

I do the usual trick of mixing the two in various ratios, and it's often
difficult to get a nice yellow as a result; most of the time you go from
orange to yellow-green without really stoping at a good yellow.

Yeah, look at the wavelength in nm.

If you're really picky, get yourself RGB LEDs and pick your own
colors.
