+# Disallow references to deprecated color variables (no-deprecated-colors)
+
+🔧 The `--fix` option on the [ESLint CLI](https://eslint.org/docs/user-guide/command-line-interface#fixing-problems) can
+automatically fix some of the problems reported by this rule.
+
+[Theming](https://primer.style/react/theming) in Primer React is made possible by a theme object that defines your
+application's colors, spacing, fonts, and more. The color variables in Primer React's
+[default theme object](https://primer.style/react/theme-reference) are pulled from
+[Primer Primitives](https://github.com/primer/primitives). When a color variable is deprecated in Primer Primitives,
+it's important to remove references to that color variable in your application before it's removed from the library.
+
+## Rule details
+
+This rule disallows references to color variables that are deprecated in
+[Primer Primitives](https://github.com/primer/primitives).
+
+👎 Examples of **incorrect** code for this rule:
+
+```jsx
+/* eslint primer-react/no-deprecated-colors: "error" */
+import {Box, themeGet} from '@primer/react'
+import styled from 'styled-components'
+
+const SystemPropExample() = () => <Box color="some.deprecated.color">Incorrect</Box>
+
+const SxPropExample() = () => <Box sx={{color: 'some.deprecated.color'}}>Incorrect</Box>
+
+const SxPropExample2() = () => <Box sx={{boxShadow: theme => `0 1px 2px ${theme.colors.some.deprecated.color}`}}>Incorrect</Box>
+
+const ThemeGetExample = styled.div`
+  color: ${themeGet('colors.some.deprecated.color')};
+`
+```
+
+👍 Examples of **correct** code for this rule:
+
+```jsx
+/* eslint primer-react/no-deprecated-colors: "error" */
+import {Box, themeGet} from '@primer/react'
+import styled from 'styled-components'
+
+const SystemPropExample() = () => <Box color="some.color">Correct</Box>
+
+const SxPropExample() = () => <Box sx={{color: 'some.color'}}>Correct</Box>
+
+const SxPropExample2() = () => <Box sx={{boxShadow: theme => `0 1px 2px ${theme.colors.some.color}`}}>Correct</Box>
+
+const ThemeGetExample = styled.div`
+  color: ${themeGet('colors.some.color')};
+`
+```
+
+## Options
+
+- `skipImportCheck` (default: `false`)
+
+  By default, the `no-deprecated-colors` rule will only check for deprecated colors used in functions and components
+  that are imported from `@primer/react`. You can disable this behavior by setting `skipImportCheck` to `true`. This is
+  useful for linting custom components that pass color-related props down to Primer React components.
+
+  ```js
+  /* eslint primer-react/no-deprecated-colors: ["warn", {"skipImportCheck": true}] */
+  import {Box} from '@primer/react'
+
+  function MyBox({color, children}) {
+    return <Box color={color}>{children}</Box>
+  }
+
+  function App() {
+    // Enabling `skipImportCheck` will find deprecated colors used like this:
+    return <MyBox color="text.primary">Hello</MyBox>
+  }
+  ```
+
+- `checkAllStrings` (default: `false`)
+
+  If `checkAllStrings` is set to `true`, the `no-deprecated-colors` rule will check for deprecated colors in all
+  strings. This is useful for catching uses of deprecated colors outside system props and the `sx` prop.
+
+  ```js
+  /* eslint primer-react/no-deprecated-colors: ["warn", {"checkAllStrings": true}] */
+  import {Box} from '@primer/react'
+
+  function ExampleComponent() {
+    const styles = {
+      // Enabling `checkAllStrings` will find deprecated colors used like this:
+      color: 'text.primary',
+    }
+    return <Box sx={styles}>Hello</Box>
+  }
+  ```
