Color Picker

Color Picker is a browser-based tool that lets you choose any color visually and instantly see its values in every common CSS format. It is useful for front-end developers, UI designers, and anyone who needs accurate color codes without switching between design tools or doing manual conversions.

Tool interface

The interface is straightforward and live — all outputs update as soon as you move the picker, with no button to press:

• A large color picker input that opens the browser's native color chooser
• An Opacity slider (0–100%) that unlocks RGBA and HSLA output
• Output fields for Hex, RGB, RGBA (when opacity is below 100%), HSL, and HSLA (when opacity is below 100%), each with an individual Copy button
• Six stat cards showing the Red, Green, Blue, Hue, Saturation, and Lightness values
• A Recent colors row that keeps up to 10 previously picked colors as clickable swatches

Tool description

Most design workflows involve colors in multiple formats. Design tools like Figma and Sketch typically export hex values, while CSS stylesheets use rgb() or hsl() for dynamic theming and opacity work. Color Picker shows all formats at once, so you can copy whichever value your current task requires without running a separate conversion.

The opacity slider adds an alpha dimension across all relevant formats. At full opacity only hex, rgb(), and hsl() are shown; as soon as you reduce it, the rgba() and hsla() fields appear with the correct decimal alpha value.

The recent colors row builds up as you use the picker. Clicking any swatch instantly reloads that color so you can compare values or copy a format you missed the first time.

Common use cases:

• Picking a color on screen and exporting it as a CSS variable in the format your project uses
• Checking the HSL breakdown of a brand hex color to build a consistent tint and shade scale
• Generating RGBA or HSLA values with custom opacity for overlays, gradients, and shadows
• Keeping a short palette of recently used colors accessible during an active design or coding session

How to use

1. Click the large color picker to open your browser's color chooser and select any color.
2. Adjust the Opacity slider if you need RGBA or HSLA values with reduced transparency.
3. Copy the value you need by clicking Copy next to Hex, RGB, HSL, or their alpha variants.
4. Continue picking colors — each confirmed selection is saved to the Recent colors row.
5. Click any swatch in Recent colors to reload a previously picked color.
