Does ink color matter?

Has anyone done any research in to which ink colour produces the most hits?

Blue is at the most visible part of the light spectrum, red at the least. for this reason, I do blue.

"most visible part"… i'm not sure i understand that…

The human eye detects blue (the bit just before violet) with better acuity than red. That's why red light doesn't screw up your night vision.

I agree with blue…. not for any scientific reasons, mind you. I've tried red, black, and blue inks and have had the best success with blue.

fact is… our eyes are best adapted to the EMR wavelengths that we perceive as green… it corresponds to the wavelength of maximum intensity of solar radiation, so there is good evolutionary reasons for that. fordjae… pick another reason for using blue. :)
