Will your brand colour survive CMYK?
Screens emit light; ink absorbs it. Load an SVG or paste a hex code to see the CMYK build, the total ink coverage and a rough colour-shift score. Nothing is uploaded, and the result is a warning, not a press proof.
Why the colour moves
A printer converts your file to cyan, magenta, yellow and black ink. Bright greens, oranges and violets often sit outside what those four inks can mix, so the conversion brings them into gamut and the brand colour moves. Large solid areas make the shift obvious; small text mostly hides it.
The table above names the CMYK build, the total ink (over 300% is usually a warning, not a target) and a ΔE score against a naive print simulation. The chroma test catches the colours most likely to be out of gamut even when the arithmetic looks calm.
What to do about it
- Accept the CMYK version as the print brand, and write down the value so the next printer matches it.
- Use a spot ink when the exact colour matters and the budget allows an extra plate.
- Keep a one-colour version for the jobs where colour matching is not worth the money.
- Ask for a physical proof on the actual stock before a large run.
