Idle defaults to black on white text, but colors text with special meanings. +For the shell, these are shell output, shell error, user output, and +user error. For Python code, at the shell prompt or in an editor, these are +keywords, builtin class and function names, names following class and +def, strings, and comments. For any text window, these are the cursor (when +present), found text (when possible), and selected text.
+Text coloring is done in the background, so uncolorized text is occasionally +visible. To change the color scheme, use the Configure IDLE dialog +Highlighting tab. The marking of debugger breakpoint lines in the editor and +text in popups and dialogs is not user-configurable.
The coloring is applied in a background “thread,” so you may occasionally see -uncolorized text. To change the color scheme, edit the [Colors] section in -config.txt.
