Color Picker Guide
Need precise pair conversion pages? Open the dedicated format converters in this section, or jump to the Code Formatter and CSS Sprites Generator for frontend workflows.
Quick start
- Pick with the color input or main Eyedropper; HEX, RGB, RGBA, HSL, HSV, and CMYK update with Copy buttons. Use the alpha slider when you need transparency.
- Use the palette row and contrast tools as needed; open a dedicated converter below Saved Colors for fixed input/output per format pair. Common questions are linked under that list.
Formulas & deeper content
Parsing rules, the sRGB pipeline, worked examples, and calculation lines for one pair (e.g. HEX → RGB) stay on that pair’s page—not repeated here.
CMYK is a simple on-screen preview here (not a printer ICC profile). The yellow note on CMYK pair pages and the Color Picker FAQ expand on non-unique CMYK↔RGB and app-to-app differences; use HEX/RGB for stable UI work.
Example uses
- Web/CSS: copy HEX, rgb(), hsl(), or rgba().
- Accessibility: WCAG contrast vs presets or a custom comparison color.
- Design: complementary, analogous, and triadic variants from the palette.
