Full details: Linked Issues checkExplanation The pull request adds React Native color handling and migration documentation, but it does not implement the directly linked issue's required shared Android string parser. The changes remove Android string parsing, shorthand expansion, named-color preservation, and invalid-input handling from the native setters. The required legacy blur-view parser path is also not shown. [ Resolution Implement and share the Android parser required by [ Full details: Out of Scope Changes checkExplanation The pull request includes platform-produced ColorValue pass-through and related native-component typing changes. The stated objectives explicitly exclude dynamic platform-color support. The remaining TypeScript, documentation, and migration changes are related to color handling.

Please ask Codex to verify whether the documentation and the website align with the new color adjustments, I noticed that this is missing in some places.

Please check for us whether this file is needed by other components. It is initially used to calculate and handle the hexadecimal color for the fallback color. However, I believe it might no longer be necessary for us.

The JSDoc for the glassTintColor property has been updated, it now accepts ColorValue instead of just a hex string.
While you're at it, please check if the JSDoc has been updated for the other components as well.

The reducedTransparencyFallbackColor property must be a ColorValue too.

| Glass tint and switch colors now use React Native's `#RGB`, `#RGBA`, `#RRGGBB`, and `#RRGGBBAA` formats. Previously Android treated eight-digit strings as `#AARRGGBB` and rejected shorthand. If you used Android-specific ARGB strings as a workaround, move the alpha byte to the end (for example, `#80FF0000` becomes `#FF000080` for half-transparent red). Six-digit colors are unchanged. | ||

This migration specification can be changed to:
"Android components now accept ColorValue, not just hex strings, for their colors."

Adjust here too, the Android blur switch accepts ColorValue.

Fix
Share Android string parsing for #RGB, #RGBA, #RRGGBB and #RRGGBBAA across glass tint and switch setters. Keep existing named-color parsing and invalid-input handling.
Compatibility / breaking changes
Behavior change: eight-digit Android strings now mean #RRGGBBAA, not Android Color.parseColor’s #AARRGGBB. Apps using an ARGB workaround must move alpha to the end (for example #80FF0000 → #FF000080). Six-digit colors are unchanged; shorthand becomes supported. No new CSS rgb()/hsl() or dynamic platform-color support is claimed.
Verification
Twenty valid/invalid Android parser cases: seven baseline failures become zero using an Android Color API double. Actual Kotlin source and generated bindings compile against RN 0.87.1; both app Android builds pass.
Combined review branch: 40 existing Jest tests across four suites, TypeScript, ESLint (three pre-existing inline-style warnings), Bob builds, web-entry graph validation and whitespace checks passed. No checked-in tests/specs were added or changed. Consumer integration passed both products’ Android Debug and iOS Simulator Debug builds, four production Metro bundles, 13 web targets and four browser-extension targets. The upstream example built for Android and iOS, exported for web, and its iOS home screen was launched and visually inspected. Physical-device, signed-release and Android runtime testing were not performed.
Closes #141
