Color grid with x and y args to visualize effects of 2D transformations?

I'm trying to get a simple kind of color chart function that I can pass x
and as arguments to. I want to have it running across by hue and up by
saturation and value. This is to illustrate 2D transformations, so I need to
have arguments that I can _inversely_ transform in order to illustrate the
effects of 2D transformations, whether linear or not.

One direct approach would seem to have nested loops, but I can't see how to
do this if the body of the For loop in Mathematica is part of the function.

Any help getting a "jump start" in this kind of thing would be a huge help
to me.

For[i = 0, i < 10, i++,

  For[j = 0, j < 10, j++,

      RegionPlot[(i < x < i + 1) && (j < y < j + 1), {x,0,10}, {y,0,10}]
