Let's say we're solving the heat equation on [0,1]x[0,1] numerically with an initial temperature distribution with values in [0,1], and we're displaying the solution with ListDensityPlot as it evolves over time. How can one specify the ColorFunction option in ListDensityPlot so that a temperature of 1 _always_ shows as red and a temperature of 0 always shows as blue (with green, yellow, orange in between)? In other words, I need a fixed mapping between function values and color.
