Description
Please note that this functions assumes that class labels are labeled consecutively, e.g,. 0, 1, 2, 3, 4, and 5
Would it be much effort to remove that restriction? I just wondered why my testcase with classes [99,100] had its contour color reversed.

Research direction
Locate the plot_decision_regions entry point and inspect how class labels are mapped to contour colors. Reproduce the reported case with classes [99, 100], then add coverage showing that arbitrary labels receive the expected colors; done means the restriction on consecutive labels is removed without reversing the contour colors.
