To get a specific color value from a color map in Matplotlib, use:

cmap = matplotlib.cm.get_cmap("autumn")
rgba = cmap(0.3)
print(rgba)
(1.0, 0.2980392156862745, 0.0, 1.0)

Here, we're getting the color representation of the value 0.3 in the color map autumn. Note that, by default, the lower and upper bounds for color maps are 0 and 1, respectively. If you call cmap(15), for instance, this will return the same result as cmap(1).
