What do the colors on the scrollbar of Jetbrains IDE's mean?

Question

Is there a list that defines what every color in the Intellij Idea scrollbar (right of the screen) means?

Answer 1

You can find/change it in Settings | Editor | Color Scheme, General:

Look for the elements that have Error Stripe Mark defined, these are:

• Error
• Warning
• Weak Warning
• Problem from Server
• Identifier under caret
• Text search result
• TODO (default one, can be customized in Settings | TODO per pattern).
