There quite a lot FAQs, eg.: Graphics/Contour.Density/DensityBlack.html : How do I render DensityGraphics so that I don't get an entirely black image? Try the following if your DensityGraphics (created by DensityPlot or ListDensityPlot) appears as all-black graphics. The Mesh may be so tight that it covers the graphic. Try using the option Mesh -> False. Under Windows, the display may be set to a color setting that causes a PostScript error. Go to the settings in the Display Control Panel. Start|Settings|Control Panels|Display|Setting Change the setting for number of colors. High Color(16-bit) should resolve the error. Last modified on Dec 28, 1999.
