Color formats explained
Designers and developers use different color formats:
HEX — #FF5733. Compact, used in CSS and design tools.
RGB — rgb(255, 87, 51). Red, Green, Blue values (0-255). Used in web and programming.
HSL — hsl(9, 100%, 60%). Hue (0-360°), Saturation (0-100%), Lightness (0-100%). Intuitive for designers.
Using a color picker
1. Click the color picker — opens a visual selector. 2. Select a hue — drag along the color spectrum. 3. Pick saturation & lightness — adjust in the square. 4. Copy the result — grab HEX, RGB, or HSL.
Easy for quick color exploration without guessing hex codes.
Color conversion
Convert between formats seamlessly:
#FF5733 ↔ rgb(255, 87, 51) ↔ hsl(9, 100%, 60%)
Useful when copying colors between tools (design software, CSS, iOS app code).
Generating harmonic palettes
A harmonic palette is a set of colors that look good together:
- Shades — darker and lighter versions of the base color.
- Complementary — opposite color on the color wheel (high contrast).
- Triadic — three colors evenly spaced (vibrant).
- Analogous — nearby colors (harmonious).
- Monochromatic — single hue with varying lightness.
Frequently asked questions
Which format should I use in CSS?
All three work. HEX is compact, RGB is precise, HSL is intuitive. Use your preference.
Can I pick colors from an image?
Current version uses a visual picker. To sample from images, upload to a color sampling tool or use browser DevTools.
What is color blindness accessibility?
Some users can't distinguish red/green or blue/yellow. Use contrast and shape cues, not just color. A contrast checker tool helps verify.
