Corrected colors closer to a5.12 version (compared with existing a6 theme). Added comments to < Color > section.
In the original file there was an excess line (177) - deleted in new version:
177 <ColorAlias name="lua action button: fill" alias="theme:bg"/>
178<ColorAlias name="lua action button: fill" alias="widget:bg"/>
