If your requirements are that the 'spacing' between all colors in the
original image and in the new image are preserved, your randomness is
going to be greatly limited. One big question is how you want to define
the distance between colors (largly which color space you want to
measure in). If you presume that the image might be using a broad
assortment of colors and distance measured but RGB distance, then the
only general transformations that preserve distances would be swapping
axis and reversing the direction of some of the axis.

Some other spaces might give slightly different options, but similar, as
'Hue' based color spaces have a polar axis which behaves a bit
differently than a cartisian axis so can't really swap with another
axis, but can have an arbitrary offset or can be flipped (so gives more
options).
