... or perhaps because you didn't gamma-adjust the colors you picked?

Note that image manipulation programs usually give you 
gamma-precorrected colors, while if you follow best practices you will 
need linear colors in POV-Ray, i.e. you'll usually want to use e.g.

   color rgb <pow(R/255, 2.2), pow(G/255, 2.2), pow(B/255, 2.2)>
