+# color theme
+
+two different color themes are supported for light and dark mode. to change the colors you have to modify files in 
+[Ron format](https://github.com/ron-rs/ron) located at git config path (same as log paths). the list of valid 
+colors can be found in [ColorDef](./src/ui/style.rs#ColorDef) struct. note that rgb colors might not be available 
+on some platforms.

+to enable light mode:

+GITUI_LIGHT=true gitui
