How to Use the Color Picker
- Click or drag inside the color square to set saturation and brightness.
- Adjust the hue using the horizontal hue slider below the square.
- Optionally adjust transparency with the alpha slider.
- Read the live HEX, RGBA, and HSL values in the fields below the picker.
- Select and copy the format you need (HEX for CSS hex codes, RGBA for transparent overlays, HSL for hsl() functions).
- Pick a new color at any time — all three fields update instantly.
What is a Color Picker?
This tool embeds the react-color SketchPicker component — a familiar sketch-style color panel with a saturation/brightness square, hue slider, and alpha slider. Selecting a color updates three read-only output fields simultaneously: HEX (like #3b82f6), RGBA (with alpha channel), and HSL (hue, saturation, lightness). Each field is labeled and ready to copy into your CSS, design tool, or code editor.
There is no server round-trip: color state lives entirely in the browser. The picker supports full alpha transparency via the alpha slider, which is reflected in the RGBA output. This is a focused single-color picker — for multi-color harmonies use the Color Palette Generator, and for CSS gradient strings use the Gradient Generator.
The SketchPicker onChange handler receives a ColorResult object containing hex, rgb, and hsl properties. These are formatted into display strings and stored in component state. The RGBA field includes the alpha value; the HSL field reflects the current hue, saturation, and lightness derived from the picker interaction.
How it works
You set color picker from palette in the live panel. Color Picker then pick colors from a palette or image. Results show as result from color picker you can copy or download.
To convert between color formats in bulk, use our Color Converter.
Usage scenarios
- CSS hex code extraction: Pick a brand blue visually, copy the HEX field, and paste it into your stylesheet or Tailwind config.
- Transparent overlay color: Set alpha to 50% on the picker, copy the RGBA string, and use it for a modal backdrop in CSS.
- Design-to-code handoff: Match a color from a mockup by eye using the picker, then copy HSL for a hsl() custom property.

Input

Output

Frequently Asked Questions
What color formats are supported?+
Our color picker supports HEX (#ffffff), RGB (255, 255, 255), HSL (360°, 100%, 100%), and HSV (360°, 100%, 100%) formats.
Can I input a specific color value?+
Yes, you can input specific HEX values or use the color picker to visually select colors. The tool will automatically convert between all supported formats.
What's the difference between RGB and HSL?+
RGB uses Red, Green, Blue values (0-255), while HSL uses Hue (0-360°), Saturation (0-100%), and Lightness (0-100%). HSL is often more intuitive for color adjustments.
Is this tool free to use?+
Yes, our color picker tool is completely free with no limitations on usage. Perfect for designers, developers, and anyone working with colors.

When to Use Color Picker
- Grabbing an exact HEX code from a color you are visualizing for a CSS stylesheet
- Copying an RGBA value with a specific alpha for a semi-transparent overlay
- Converting a color you picked visually into HSL for use in a hsl() CSS function
- Quick color selection during frontend development without leaving the browser
Advantages
- Familiar Sketch-style visual picker with hue and alpha sliders
- Three formats displayed simultaneously (HEX, RGBA, HSL)
- Instant live updates on every picker interaction
- No signup or server dependency
Tips
- Use HEX for most CSS color properties; switch to RGBA when you need explicit alpha control.
- HSL values from the picker map directly to CSS hsl() and hsla() functions.
- Pair with the Color Converter if you need additional format transforms beyond what the picker displays.
- Copy RGBA when building rgba() overlays in Tailwind arbitrary values or inline styles.
Common Mistakes
Expecting palette or gradient generation here — use Color Palette Generator or Gradient Generator instead.
Copying HEX when you need alpha — HEX from the picker does not include transparency; use RGBA.
Assuming copied values include CSS function wrappers — copy and wrap in rgba() or hsl() as needed.
Summary
Pick any color on the SketchPicker, read the live HEX, RGBA, and HSL values, and copy the format you need — a fast single-color picker that runs entirely in your browser.
