What is wrong then?? No, colors is a sequence of colors in this example, and I think that even if it did not give an error, it would not do what you want; but yes, I don't think this should give an error. And, on my system, a rough equivalent does not. What mpl version are you using?
Regardless, I think what you want is more like this: scatter(x, y, c=arange(len(x)), cmap=cm.spectral) Then the colors will be determined from a table lookup in the spectral colormap based on the floating point values in c, with the smallest value mapped to the first color and the largest value mapped to tha last.
