It depends on the wavelenght. To say 808nm is a very dim brown colour.
All wavelenghts over 808 are completely invisible to our eyes. :beer:
To me it appears as a dim reddish color actually.
For the most part when dealing with IR you're talking about wavelengths of over 808nm or much much higher as quemofox pointed out... so I'll stand by what I said... IR has no color (at least to us humans with mark one eyeballs).
