Why Doesn’t the TypeScript ColorValue Type Allow Numeric Colors in React Native?

[polovi]

In React Native, numeric color values (e.g., 0xff00ff00 for RGBA color) are valid and work at runtime. However, the TypeScript type ColorValue only allows string, which leads to type errors when using numeric colors:

<View style={{ backgroundColor: 0xff0000ff }} />  // Works at runtime, but TypeScript complains

Since React Native itself supports numeric colors, why isn't ColorValue defined to allow them? Is there a specific reason for this restriction, or is it an oversight in the type definitions?

What’s the best way to handle this in a TypeScript project without disabling type checking?

Thanks!
