the color of the BBs has little to do with the wavelength of light they can absorb. the material reacts best with higher wavelengths.
infra red - visible - Ultra Violet
long(low) - mid - short(high)
thats why blue works better than white and UV works better than both, and a red high power laser does shit all.
the mcd value is how bright they are. the higer the mcd, the brighter the LEDs
