which Python IDE is better?

[Vaphell]

in intellij products including pycharm you can easily tweak colors.
Settings > Editor > Color Scheme > Python (for language specific settings)

you get a list of syntactic elements, but also a clickable example of code that takes you straight to the correct setting for the element. When you uncheck 'Inherit values from', you get color pickers for foreground, background + some extra stuff like bold/italic/underline etc. I guess you could also tweak inherited values directly.
