In Yellowbrick visiualization library, the default color for the classification report is red: from lighter to darker tones. Is there a way to change this color and use green, blue, etc.?
when defining the visualizer, you can set a color sequence(cmap).
viz = ClassificationReport(model, cmap='PuRd')
viz.score(X_test, y_test)
You can find the different color sequences at
