How can I change the background color In Mathematica?
– You can change the Background color in your plots with the “Background” option, e.g: Plot[Sin[x], {x,0,2Pi}, Background->GrayLevel[0.9]] Mathematica also picks up on the global defaults like the default color that is set by your X server. It will use this color definition by default. The default color is usually defined in your .Xresources file.
