Understanding Color Formats
HEX Color HEX is the most common format for web design. It uses a hash sign followed by six hexadecimal digits.
| HEX | Red | Green | Blue | Color |
|---|---|---|---|---|
| #FF0000 | 255 | 0 | 0 | Red |
| #00FF00 | 0 | 255 | 0 | Green |
| #0000FF | 0 | 0 | 255 | Blue |
| #FFFFFF | 255 | 255 | 255 | White |
| #000000 | 0 | 0 | 0 | Black |
**Short HEX:** You can also use 3-digit shorthand — #F00 is the same as #FF0000.
RGB Color RGB stands for Red, Green, Blue. Each value ranges from 0 to 255.
| Color | R | G | B |
|---|---|---|---|
| Red | 255 | 0 | 0 |
| Orange | 255 | 165 | 0 |
| Yellow | 255 | 255 | 0 |
| Green | 0 | 128 | 0 |
| Blue | 0 | 0 | 255 |
| Purple | 128 | 0 | 128 |
HSL Color HSL stands for Hue, Saturation, Lightness. This format is more intuitive for humans.
- **Hue** — 0 to 360 degrees (position on the color wheel)
- **Saturation** — 0% (gray) to 100% (full color)
- **Lightness** — 0% (black) to 100% (white)
| Hue Range | Color |
|---|---|
| 0 - 60 | Red to Yellow |
| 60 - 120 | Yellow to Green |
| 120 - 180 | Green to Cyan |
| 180 - 240 | Cyan to Blue |
| 240 - 300 | Blue to Magenta |

Frequently Asked Questions
**Q: What is the difference between RGB and HEX?** A: They represent the same color in different ways. HEX is hexadecimal notation of RGB values. #FF0000 = rgb(255, 0, 0).
**Q: When should I use HSL instead of RGB?** A: Use HSL when you need to adjust hue, saturation, or lightness independently. HSL is more intuitive for creating color variations.
**Q: What is CMYK and when do I need it?** A: CMYK is used for print design. If you are designing for physical printing, you need CMYK values.
