Understanding RGB to HEX Conversion
RGB (Red, Green, Blue) uses decimal values (0-255) for each color channel. HEX uses hexadecimal notation (00-FF) for the same values.
Conversion Process
- Convert each RGB value (0-255) to hexadecimal (00-FF)
- Combine in order: #RRGGBB
- Example: rgb(255, 128, 0) → #FF8000
Color Format Comparison
- HEX: #FF5733 (6 characters, compact)
- RGB: rgb(255, 87, 51) (longer, more readable)
- RGBA: rgba(255, 87, 51, 0.8) (includes transparency)
- HSL: hsl(9, 100%, 60%) (hue, saturation, lightness)
When to Use Each Format
- HEX: Static colors in CSS, design systems
- RGB: When manipulating colors with JavaScript
- RGBA: When you need transparency/opacity
- HSL: When adjusting brightness or saturation
💡 Pro Tip:
Use HEX for solid colors in CSS files, and RGBA when you need to add opacity. Modern CSS also supports 8-digit HEX (#RRGGBBAA) for transparency!
Shorthand HEX Codes
When both digits of each color channel are the same, you can use shorthand:
- #FFFFFF → #FFF (white)
- #000000 → #000 (black)
- #FF0000 → #F00 (red)
- #00FF00 → #0F0 (green)
