I have several primitive figures to pass to the Graphics function to draw. These figures are weighed with some values, so I'd like to assign a color in accordance with some ColorFunction, say "TemperatureMap". Is it possible to use Graphics like this?

tr = Triangle[{{0, 0}, {0.25, 0}, {0.125, 0.25}}];
value=0.8;
Graphics[{ColorFunction -> "TemperatureMap"[value], tr}]

  • $\begingroup$ You have a list of Graphics primitives, and a list of values? You'd like for each primitive to have a single color according to its value? $\endgroup$

Yes, you can, but you should be aware of the values that the color scheme (TemperatureMap in this case) can take:

tr = Triangle[{{0, 0}, {0.25, 0}, {0.125, 0.25}}];
Graphics@{ColorData["TemperatureMap"][#], tr} & /@ Range[0, 1, 0.1]
