Color Picker
Free Online Color Picker – HEX, RGB & HSL Color Code Generator
Use the picker when you need the same color expressed for different contexts. Select a color visually, type a six-digit HEX value, or adjust its red, green, and blue channels. The page shows equivalent HEX, RGB, and HSL values so a color chosen for a mockup can be copied into CSS or another design tool.
HEX represents red, green, and blue as hexadecimal pairs; RGB shows each channel from 0 to 255; HSL describes hue, saturation, and lightness. HSL is often easier when you want a lighter, darker, or less saturated variation of a known color. Recent colors are kept in the browser for convenient comparison.

HEX Color Code
HEX (Hexadecimal) is the most common format used in CSS and HTML. Widely used for website backgrounds, text colors, buttons, and branding.
RGB Color Code
RGB stands for Red, Green, and Blue. Each value ranges from 0 to 255. Commonly used in CSS styling, digital screens, and web animations.
HSL Color Code
HSL stands for Hue, Saturation, and Lightness. Useful for creating color variations, adjusting brightness, and generating consistent UI palettes.
How to Use the Color Picker
- Drag the RGB sliders to adjust red, green, and blue values
- Or click "Pick a Color" to choose a color visually
- The HEX, RGB, and HSL values update automatically
- Click the copy icon to copy the color code
- Paste it directly into your CSS, design software, or project
Good to Know About Color Values
- All three formats describe one color. HEX, RGB, and HSL update together as you change the selection.
- HSL is best for adjusting. Keep the hue and change the lightness to make a tint or a shade.
- Shorthand HEX works. A value like #0AF expands to #00AAFF automatically.
- Screens vary. The same code can look slightly different depending on a display's calibration.
- Check contrast for text. A readable pair needs enough contrast, which the values alone do not guarantee.
