To override the files you need to:
1. Go to Options/Show REAPER Resources path
2. Open ColorThemes folder
3. Extract Default_6.0.ReaperThemeZip
4. Open Default_6.0_unpacked folder
5. Paste new png files and overwrite the originals
6. Zip Default_6.0_unpacked folder and Default_6.0_unpacked.ReaperTheme file together
8. Rename newly created zip file to Default_6.0-my_mod.ReaperThemeZip (or similar)
9. Load new Default_6.0-my_mod theme in REAPER.
