HEX to LAB Converter

Advanced color conversion tool for designers and developers

HEX Color
LAB Color
Understanding Your Conversion: LAB (CIELAB) is a device-independent color space designed to approximate human vision. Unlike HEX/RGB which are device-dependent, LAB provides consistent color measurements regardless of output medium.
Color Values
Note: RGB and CMYK values are rounded to integers for display. LAB conversions maintain floating-point precision internally.
Professional Color Workflow Guidance
When to use LAB color values:
  • Print Production: LAB provides consistent color specification between RGB screens and CMYK presses
  • Accessibility Compliance: Use L* (lightness) values to ensure sufficient contrast ratios
  • Brand Systems: Define colors in LAB for consistent reproduction across digital and print
  • Color Matching: Use ΔE calculations to ensure color consistency between different outputs
Important Limitations to Consider:
  • This tool uses the standard D65 illuminant and 2° observer angle
  • Some highly saturated RGB colors may be outside printable CMYK gamut
  • Monitor calibration affects visual perception of converted colors
  • For critical print work, always obtain physical proofs
Color harmonies are generated in LAB color space for perceptual uniformity.
LAB-Based Harmonies Advantage: Traditional color wheels use equal hue increments, but LAB harmonies maintain perceptual balance. Colors appear equally spaced to the human eye, making them more effective for design systems and accessible palettes.

Bulk Conversion Use Cases: Convert design system tokens, process brand color libraries, prepare print production files, or analyze color palettes from other sources. All conversions maintain the same precision as single-color mode.

Color Conversion FAQ
How accurate is this conversion?

This tool uses industry-standard CIE 1976 conversion formulas. Accuracy is suitable for design and prepress workflows. For scientific colorimetry, specialized instruments are required.

Why do colors look different on my printer?

Monitor RGB and printer CMYK have different color gamuts. LAB conversion helps bridge this gap, but physical proofs are essential for critical color matching.

Can I use LAB values in CSS or design software?

Most design software (Adobe Creative Cloud, Sketch, Figma) supports LAB input. For web use, convert LAB back to HEX or RGB, as CSS doesn't support LAB natively.

What's the difference between LAB and L*a*b*?

They refer to the same CIELAB color space. The notation L*a*b* emphasizes the three components: Lightness (L*), green-red (a*), and blue-yellow (b*).
