Website

Here is a blogpost where (the then new) theming is explained:
https://blog.jetbrains.com/platform/2021/10/themes-in-intellij-based-ides/

Example theme file

(taken from above blogpost):

{
 "name": "My Theme",
 "dark": true,
 "author": "JetBrains",
 "editorScheme": "/themes/my.xml",
 "colors": {
   "colorPrimary": "#3b3531",
   "colorSecondary": "#342e2b"
 },
 "ui": {
   "*": {
     "background": "colorPrimary",
     "separatorColor": "colorPrimary",
     "borderColor": "colorSecondary"
   }
 },

 "background": {
   "image": "/background.png",
   "transparency": 50,
   "fill": "plain",
   "anchor": "bottom_right"
 }

<scheme name="My Theme" version="1" parent_scheme="Darcula">
   <colors>
       <option name="CARET_ROW_COLOR" value="372513" />
       <option name="GUTTER_BACKGROUND" value="372513" />
   </colors>
   <attributes>

           <value>
               <option name="FOREGROUND" value="C67E48" />
               <option name="BACKGROUND" value="291918" />
               <option name="EFFECT_TYPE" value="5" />
           </value>
       </option>
   </attributes>
</scheme>

Additional theme information

There is already https://github.com/tamzinselvi/themer-jetbrains that is a template for Jetbrains IDEs (also mentioned in #22) but at some point Jetbrains has changed the theming from the .icls files to this more complex setup that allows for styling both the UI as well as the colors for editor. In addition, that themer-jetbrains repo does not seem to be compatible with the current version of themer.
