Based on the color snapshot by Huygens of the surface of Titan, it seems it wouldn't be hard to tint the latest radar image of Titan to roughly the same color.

I tried it with Irfanview and it didn't work. Any ideas?

Thanks!

The Huygens image is actually greyscale - all the coloured versions out there are artificial.

There''s a color photo of the surface that says, "Color photo" on Solarviews. It's a colorized photo?

Yes, it is. It's colorized based on visual spectra measured by the DISR spectrometer. The spectrometer resolution is so low that it basically just averaged everything that would be visible on the ground in that surface shot into one color. It's not a terribly bad representation and there's probably not that much color variation in the scene anyway, but in reality the pebbles could be a slightly different color for all we know.
