Color Chooser won't show up upon selecting it in the menu

Anastasia said that the UI was unclear and that it was buggy. The only concrete feedback was that it just wouldn't open. If we clearly find other issues with it upon resolving the opening issue, we should create another issue.

And here's the java error:
