The answer is that they must look different to other people than they do to you.

Im not sure exactly what you mean but if you mean can a colourblind person see colours of course we can we just see them differently and sometimes more obscurely. I personally find it annoying when people who know I'm colourblind ask me stuff like that. If you mean do colourblind and non colourblind people see colours differently; yes. Colourblindness is caused by a slight "difference from the normal" of the yellow spot (cluster of photosensitive cells that allow colours to be distinguished)
