Color Picker and Converter

When this tool is a good fit

Color Picker and Converter helps when you need copy-ready HEX, RGB, HSL, and HSV values plus a reusable local palette from a HEX value, RGB channels, HSL values, or a color chosen with the picker. It is most useful for choosing interface colors, converting design values, checking brand colors, and building small working palettes. The notes below focus on the settings that matter, the checks worth doing before you export, and the limits that tend to cause mistakes.

• Takes a HEX value, RGB channels, HSL values, or a color chosen with the picker.
• Lets you adjust which color model to edit, whether to sample from the screen, and which format to copy.
• Calls out what to review: channel values, saved palette entries, and whether the chosen color works with nearby UI states.
• Produces copy-ready HEX, RGB, HSL, and HSV values plus a reusable local palette.
• Fits common jobs such as choosing interface colors, converting design values, checking brand colors, and building small working palettes.

Example jobs

• Convert a brand HEX color into RGB, HSL, and HSV values for design handoff.
• Use the browser color picker to choose a UI color and copy the CSS-ready value.
• Save frequently used colors into a small local palette for later sessions.

How to use Color Picker and Converter

1. Prepare a HEX value, RGB channels, HSL values, or a color chosen with the picker.
2. Set which color model to edit, whether to sample from the screen, and which format to copy before running the tool.
3. Generate or process the result, then review channel values, saved palette entries, and whether the chosen color works with nearby UI states.
4. Copy, export, or download copy-ready HEX, RGB, HSL, and HSV values plus a reusable local palette.
5. Run a second pass if the destination system, document, or workflow has stricter requirements.

What to know before you use it

• The native browser color input controls the selected HEX value.
• RGB, HSL, and HSV values are calculated from the current color in local JavaScript.
• Saved colors are stored in localStorage on the current browser only.
• HEX and RGB are direct screen color representations, while HSL is often easier for adjusting lightness and saturation.
• Browser eyedropper support depends on the browser, permissions, and whether the page is running in a secure context.

Checks and edge cases

• Adjust lightness in HSL when making hover, active, and disabled states from the same base color.
• Pair the picker with color reference pages when you need named color context or contrast notes.

How your data is handled

Color values and saved swatches stay in your browser. Toolumina does not upload or sync your palette.
