Mapping colours in DensityPlot

I am using the following command to do a DensityPlot in grayscale. The
grayscale range is from 0-255, but I need to map my function to a grey-level
maximum of 200. How do I define a new GrayLevel with a max gray level of
200? (Or alternately change the mapping so make the max level 200?)
DensityPlot[Mod[elementphase[x, y], 2 \[Pi]], {x, -0.008, 0.008},
{y, -0.006, 0.006}, PlotRange -> All, PlotPoints -> 120, ColorFunction ->
GrayLevel, Frame -> False, ImageSize -> {{0, 800}, {0, 600}}, AspectRatio ->
600/800]
Any suggestions will be appreciated, although I'm a Mathematica newbie, so
an example of what to do rather than a broad instruction would be
invaluable.
