If, on the other hand, you mean "Can I make (and see) a picture containing
all available colours that can be used (in
some specific colour-space)?", then the answer is approximately "yes", if
you are using 8 bit colour (you just need a
4096x4096) image, and probably "no", if you are thinking of 12,14, or 16
bit colours.
