Convert RGB to LAB
Convert RGB to CIE Lab color values. Referenced to the D65 white point so it round-trips cleanly with sRGB — note this differs from the D50 reference common in print workflows.
Overview
Color Converter handles the most common color-format conversions — HEX, RGB, CMYK, LAB, and HSL — with a focused, deeplinkable page for each direction. Every conversion runs instantly in your browser, and URLs can carry a prefilled value so you can share or bookmark a specific conversion. Exact conversions (HEX/RGB/HSL) are flagged as such; approximate ones (CMYK, LAB) carry a clear note about what's approximated and why.
Key Features
- Convert between HEX, RGB, CMYK, LAB, and HSL
- Deeplinkable — prefill the input via a URL parameter
- One-click copy of the converted value
- Clear notes on where a conversion is exact vs. approximate
- Link straight into the full Color Editor for more formats and tools
- 100% client-side — nothing you enter is uploaded
Common Use Cases
- Getting a print-ready starting point — Convert a brand HEX color to CMYK for a print vendor, with a clear caveat that it's an uncalibrated approximation.
- Moving a color into CSS — Convert RGB or HSL values from a design file into the exact format your stylesheet needs.
- Sharing a conversion with a teammate — Send a URL with the value already filled in, so they see the exact conversion you're looking at.
