Create IntelliJ ui themes from either a intellij editor theme or by supplying a json map of theme colors.
Go to releases, download your zip archive and extract it.
Create custom ui theme folder by following these instructions.
If you do not have an editor theme, you can create one with themecreator.
Generate the ui theme with
iui generate <path to editor theme> templ.txt.
Alternatively you can customize the ThemeColors.json file with your colors, and generate the ui theme with
iui generate --json ThemeColors.json templ.txt.
Replace the .theme.json file in the plugin's resources folder with your generated file, make sure to fill out the author field, press the run button and admire your new theme.
