OKLAB to LAB
Color Convert Engine
Enter a color in any supported format; the engine outputs every other color space.
Input Mode
Accepts #RGB or #RRGGBB, with or without #.
Preview
#1E40AF
Preview uses the sRGB color space.
Output — all color spaces
How to use
- Provide OKLAB tuples from modern color tooling, compare intermediate mixes against legacy linear RGB blends if you are migrating palettes.
- Mixing OKLAB with legacy sRGB assumptions without adjustment can shift midpoint colors in gradients.
- Audit gradients and hover ramps in real UI after conversion.
FAQ
What is OKLAB to LAB used for?
OKLAB to LAB is used when your source color is expressed as OKLAB coordinates—a perceptually uniform space popular for resilient gradients and interpolation but your destination expects CIELAB coordinates (`L*`, `a*`, `b*`) used for perceptual comparisons—common when aligning design tools, CSS, print specs, or APIs.

When should I prefer OKLAB?
Use OKLAB when smoothing blends or judging perceptual distance matters more than legacy picker ergonomics.
Introduction
OKLAB is a newer perceptually uniform space built for predictable interpolation and distance judgments—common when blending gradients or evaluating pairs mathematically. That is what we treat as the from (OKLAB) color encoding on this page.
CIELAB (L*, a*, b*) measures lightness plus green–red and blue–yellow opponent axes in a space designed for perceptually even spacing between colors. That is the to (LAB) encoding you get after conversion.
A OKLAB to LAB converter bridges them when your pipeline outputs OKLAB but the next step expects LAB—without redoing the coordinate math by hand.
What is OKLAB to LAB?
OKLAB to LAB maps colors described in OKLAB coordinates—a perceptually uniform space popular for resilient gradients and interpolation into CIELAB coordinates (L*, a*, b*) used for perceptual comparisons. The perceptual aim is the same color expressed with different coordinates—ideal when downstream systems disagree on notation.
Key Features
Fast conversion helps when you are juggling OKLAB inputs against LAB consumers in the same sprint.
Live preview catches transcription mistakes early, especially when channels have different ranges or units.
Copy-ready output reduces slack-and-paste errors moving from spreadsheets or PDF specs into code.
Common Use Cases
- Shipping UI tokens where APIs expose OKLAB but theme files require LAB.
- Preparing brand palettes for mixed pipelines—web RGB alongside print CMYK or perceptual LAB QA.
- Debugging divergent pickers by exporting one canonical mix and re-importing it elsewhere.
Best Practices
- Normalize inputs (confirm units and ranges) before trusting downstream diffs.
- Compare previews on both light and dark chrome when contrast ratios matter for accessibility.
- Bookmark the inverse LAB to OKLAB when you frequently round-trip edits.
