I have a plugin with tool window, and I want user to have ability to change colors of it. In other words, I want to add section with colors under "Settings / Editor / Color Scheme" so user may change it.
I've have read Platform SDK about themes https://jetbrains.org/intellij/sdk/docs/reference_guide/ui_themes/themes_intro.html - doesn't help
I've created test plugin like here https://github.com/JetBrains/intellij-sdk-docs/tree/master/code_samples/theme_basics - it doesn't have configurable colors either (only hardcoded)
Please, show me some directions :)
