If you happen to know an analytic form that connect a parameter running
between 0 and 1 and the value of your RGB channels you can do something
like this:
phasecolor[x_] := RGBColor[-Cos[x/2] + 1, (-Cos[(\[Pi] + x)^2/(2 \[Pi])]
+ 1)/
2, (-Cos[(\[Pi] - x)^2/(2 \[Pi])] + 1)/2];
DensityPlot[Cos[x y], {x, -5, 5}, {y, -5, 5}, ColorFunction -> phasecolor]
Best
