RGB vs HEX
Differences, use cases, and when to use each
RGB and HEX represent the same colors in different notations. RGB uses decimal values (0-255) for red, green, blue channels. HEX uses hexadecimal (00-FF). They're functionally identical — the choice is about readability and convention.

When to Use Each
When to Use RGB
Use RGB when you need to manipulate individual color channels programmatically, or when alpha transparency is needed (rgba). RGB values are more intuitive for understanding color composition.
When to Use HEX
Use HEX for CSS stylesheets where conciseness matters. HEX is the most common color notation in web development and design tools. Shorthand (#F00) is even more compact.
