Summary
Enter HSV values and instantly get the equivalent CIE L*a*b* coordinates with a live color preview.
How it works
- Enter a Hue (0–360), Saturation (0–100%), and Value (0–100%) in the input fields.
- The CIE L*, a*, and b* values update instantly as you type or drag the sliders.
- Use the color picker to choose a color visually — the HSV inputs sync automatically.
- Click any Copy button to copy individual L*, a*, or b* values.
- Click "Copy lab()" to copy the full lab() CSS string to your clipboard.
Use cases
- Convert design-tool HSV colors to perceptually uniform LAB for color difference calculations.
- Prepare HSV-defined colors for image processing pipelines that operate in LAB space.
- Measure perceptual distance between two colors by converting both to LAB and computing delta E.
- Convert brand palette colors expressed in HSV to LAB for accessibility research.
- Generate LAB values for ICC profile work or color science experiments from HSV sources.
- Cross-reference HSV picker values with CIE LAB for print or textile production.
