I want to use matplotlib's colormaps to map this number to a color, but not plot anything. Basically, I want to be able to choose the colormap with mpl.cm.autumn for example, use mpl.colors.Normalize(vmin = -20, vmax = 10) to set the range, and then map x to the corresponding color.

Matplotlib recognizes the following formats to specify a color. RGB or RGBA (red, green, blue, alpha) tuple of float values in a closed interval [0, 1]. Case-insensitive hex RGB or RGBA string. Case-insensitive RGB or RGBA string equivalent hex shorthand of duplicated characters.

Mar 15, 2021 · As far as I know, you need at least 3 values (RGB) to represent a color. Here's the full code. since your shape is (800,400), and not (800,400,3), you only have one channel. So its black and white. matplotlib is just displaying it using the viridis color map, which is the default.
