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 Jacopo On 11/21/2011 10:28 AM, Darau, M. wrote: > Hello, > > Is it possible to define a new gradient color scheme to use in DensityPlot? If so, how can I do that? I know the RGB of the end colors, and maybe 2-3 intermediate ones. > > Thanks, > Mirela > >
