@ -15,6 +15,30 @@ Colors are defined by six-digit RGB or eight-digit RGBA hexadecimal notation.
When learning new syntax, it is often useful to have some existing implementations for reference.
For example, refer to the [Theme description file](upsource:///platform/platform-resources/src/themes/HighContrast.theme.json) for the IntelliJ IDEA _High Contrast_ Theme.
## Defining Named Colors
Colors can always be defined individually as six-digit RGB or eight-digit RGBA hexadecimal notation.
However, Theme definitions often use the same color in multiple places.
Maintaining a Theme is more manageable if _Named Colors_ are globally defined in a `colors {}` block as part of the `*.theme.json` file.
After that, the Named Color can be used instead of a hexadecimal description of the color.
For example, defining the Named Color `basicBackground` and then using it to set the background color for panels.
(Don't be concerned with the `"ui"` syntax in the example below, it will be discussed in [Custom UI Control Colors](#custom-ui-control-colors).)

{
"name": "theme_basics",
"dark": false,
"author": "IntelliJ Platform SDK",
"editorScheme": "/Lightning.xml",
"colors": {
"basicBackground": "#E1E1E1"
},
"ui": {
"Panel.background": "basicBackground"
}
}
```
## Customizing Icons
UI themes can customize the color of default IntelliJ IDEA UI icons, or substitute custom icons for the default ones.
Customization is done by adding an `"icons": {}` section to the Theme description file.

In the following example the `key` - the default red color (#DB5860) used for `Action` icons in the _Light_ Theme - is overridden to the `value` of a different color (#D61A26):
