Understanding RGB vs HEX
Digital screens create colors by mixing Red, Green, and Blue (RGB) light. Each channel is represented by a decimal value from 0 to 255. In web development, we convert these decimal triplets into a single 6-digit base-16 (hexadecimal) string.
This conversion isn't just aesthetic; hexadecimal codes are more efficient for data storage and are the native way modern browsers process color information in CSS and SVG.
Key Takeaways
- Component Range: Each RGB component must be an integer between 0 and 255.
- Shorthand HEX: Some colors like #FFFFFF can be written as #FFF, but 6-digit codes are more precise.
- Safe Usage: Always include the '#' symbol when using these codes in your project's CSS files.
