在Matplotlib等高线图中选择颜色

Hello all of matplotlib experts! I have not found description in matplotlib examples of how can I set which colours I want each area to be. Is it possible to set the colours myself instead of matplotlib automatically assign them?

The contour map that I obtained so far looks like this:

Any other recommendations on how to produce readable contour maps will be very much appreciated!

Check out this example . You can set up your own colormap colors like this:

cmap = mpl.colors.ListedColormap(['r', 'g', 'b', 'c'])

You can also select from the existing colormap options
