Refactor color utilities and update type handling (#117)

- Removed unused type definitions related to CSS colors in color.ts.
- Updated the Serializable type in types-utils.ts to replace CssColor with string for better type consistency.

These changes streamline the color utility functions and enhance type safety across the codebase.
