    About Color Picker

    The Automarkly Color Picker is a free online tool that lets you choose any color and instantly see its values in HEX, RGB and HSL formats. Whether you are a web designer building a style guide, a developer implementing a design system, a digital artist matching a palette, or a student learning about color theory, this tool gives you accurate color codes the moment you select them. There is no need to switch between multiple tools — every common format is displayed together in one clean panel.

    Colors on the web are represented in several formats. HEX codes (like #4CAF50) are compact and widely used in CSS and design tools. RGB values (like rgb(76, 175, 80)) describe colors as combinations of red, green and blue light, which is how screens produce color. HSL (hue, saturation, lightness) represents colors in a way that is more intuitive for humans, making it easier to adjust a color's shade or tint. Understanding all three formats is essential for anyone working with digital color.

    Our picker uses the browser's native color input, which provides a full-featured color selection interface on every device. As you pick a color, the tool instantly computes and displays the equivalent HEX, RGB and HSL values, along with a large preview swatch. You can also type a HEX code directly into the input field to look up any specific color. Each format has a one-click copy button, so you can grab the exact value you need and paste it straight into your code or design software.

    Everything runs in your browser, so there are no accounts, no tracking, and no delays. The tool works offline once loaded and is fully responsive for use on phones, tablets, and desktops. It is a fast, reliable reference for anyone who works with color on a regular basis.

    How to Use Color Picker

    Click the color swatch to open your browser's native color picker.

    2

    Select any color from the palette or enter a HEX code in the input field.

    3

    View the automatically converted RGB and HSL values in the results panel.

    4

    Click the copy button next to any format to copy it to your clipboard.

    5

    Paste the color value into your CSS, design tool, or document.

    Key Benefits

    Instant conversion between HEX, RGB and HSL color formats.
    Large live preview swatch of the selected color.
    Direct HEX code input for looking up specific colors.
    One-click copy for each format value.
    100% client-side: no data sent to any server.

    Common Use Cases

    CSS development: pick #4CAF50 → get rgb(76, 175, 80) → paste into CSS as `background-color: rgb(76, 175, 80);`.
    Design system: pick a brand color #2563EB → get HSL hsl(217, 91%, 60%) → create lighter/darker variants by adjusting lightness.
    Accessibility check: pick text color #666666 → get rgb(102, 102, 102) → verify contrast ratio against background using WCAG checker.
    Figma handoff: pick a color from a mockup → copy the HEX value → paste into Figma's color input field.
    Cross-tool consistency: pick #FF5722 → get all three formats at once → share HEX with designer, RGB with developer, HSL with artist.

    Frequently Asked Questions

    What is the difference between HEX, RGB and HSL?

    HEX is a compact 6-digit hexadecimal code. RGB expresses a color as red, green and blue values from 0-255. HSL describes color by hue (0-360 degrees), saturation and lightness percentages, which is often more intuitive for adjusting shades.

    Can I enter a HEX code to find its RGB value?

    Yes. Type any 6-digit HEX code (with or without the # prefix) into the input field, and the RGB and HSL equivalents are calculated and displayed instantly.

    Is the Color Picker free to use?

    Yes. Like all Automarkly tools, the Color Picker is completely free, requires no sign-up, and does not collect any personal data.

    Does the tool work on mobile devices?

    Yes. It uses the browser's native color input, which provides a touch-friendly color selection interface on smartphones and tablets.

    Can I copy multiple color formats?

    Yes. Each format (HEX, RGB, HSL, and decimal RGB) has its own copy button, so you can copy whichever format you need for your project.

    Tips & Best Practices

    Use HSL when you need to create color variations — adjusting hue shifts the color, saturation controls intensity, and lightness controls brightness.
    HEX codes are case-insensitive (#FF5722 and #ff5722 are identical) and can be shortened to 3 digits when both digits match (e.g. #FFF = #FFFFFF).
    For accessible design, ensure a contrast ratio of at least 4.5:1 between text and background colors — use our WCAG Contrast Checker.
    RGB is additive color mixing (for screens), while CMYK is subtractive (for print) — they produce different color ranges.
    When building a design system, define colors as HSL variables for easy theme adjustments across light and dark modes.
    Test your color choices on different devices — screens can render colors differently due to calibration and technology.

    Conclusion

    The Color Picker gives you instant, accurate color values in HEX, RGB, and HSL formats with one-click copying, making it an essential tool for designers, developers, and artists. Whether you're building a design system, matching a brand palette, or learning color theory, this tool provides the exact codes you need in real time.
