How to differentiate colors on a k-means cluster plot

[soniavsd]

How could I tell which categories each color stood for on this graph?

@soniavsd the way that you can differentiate the colors is by printing out the y_pred labels variable side-by-side with the list of countries that match those points. If you separate all of the names of the country by their corresponding y_pred cluster number, you can get an idea as to which points are clustered together (and then infer reasons/possible explanations as to why those points may be clustered together).
