AI Color Transfer
Measure precise colour difference between two swatches using CIEDE2000 Delta E — the industry-standard perception-correct formula. Free account includes 100 credits.
Why Delta E is the only number that matters for colour QC
If you've ever argued with a printer about whether a production run matches the approved swatch, Delta E is the number that settles the argument. It's a perception-correct measure of how different two colours are — ΔE under 1.0 means humans can't tell them apart, under 2.0 means only trained eyes notice, above 3.0 means the difference is commercially unacceptable.
CIEDE2000 is the current industry standard formula (older ones — CIE76, CIE94 — have known errors in how they weight hue vs lightness). Our tool uses CIEDE2000 exclusively, matching what's specified in textile QC contracts, automotive colour spec sheets, and brand-guideline documents.
Use it to validate production samples against brand Pantones, compare batches from different manufacturers, or audit a dye house's consistency over time. Who uses it: textile quality managers, fashion brand merchandisers, print shop QC operators, and anyone writing 'ΔE ≤ 1.5' into a production contract who needs to actually measure it.
