Color Picker and Converter

Good times to use it

Use Color Picker and Converter for choosing interface colors, converting design values, checking brand colors, and building small working palettes. It works well when you want copy-ready HEX, RGB, HSL, and HSV values plus a reusable local palette and do not need a bigger workflow around it.

• Best fit: choosing interface colors, converting design values, checking brand colors, and building small working palettes.
• You start with a HEX value, RGB channels, HSL values, or a color chosen with the picker.
• The useful choices are which color model to edit, whether to sample from the screen, and which format to copy.
• Check channel values, saved palette entries, and whether the chosen color works with nearby UI states.
• You end up with copy-ready HEX, RGB, HSL, and HSV values plus a reusable local palette.

Use Color Picker and Converter like this

1. Start with a HEX value, RGB channels, HSL values, or a color chosen with the picker.
2. Choose which color model to edit, whether to sample from the screen, and which format to copy.
3. Run the tool once, 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. Open the export at the size people will actually see before you publish it.

Easy ways to ruin the result

• 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.
• 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.

What changes the output

• 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.

How your data is handled

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