BusiColor
Two colours side by side in every format, with the real difference between them. The difference is measured with CIEDE2000, the formula the industry uses, not the straight distance in RGB that almost every free tool computes. Load your own .ase swatch books; nothing leaves your browser.

About this tool
Two colours side by side in every format, with the real difference between them. The difference is measured with CIEDE2000, the formula the industry uses, not the straight distance in RGB that almost every free tool computes. Load your own .ase swatch books; nothing leaves your browser.
How it works
1
Set colour A and B: type a hex value, or pick one from your library.
2
Read the real difference. The number in the middle is ΔE2000, the formula the industry uses, with a verdict in plain words underneath.
3
All formats side by side: HEX, RGB, HSL, Lab, LCh and CMYK. The CMYK figures are marked as an approximation, because without an ICC profile there is no correct one.
4
Load your own swatch books: drop an .ase from Illustrator, or paste a list. No RAL or Pantone values are shipped, because those are licensed. Everything stays in your browser.
5
The contrast between A and B is shown as well. On a sign that is not a web rule but legibility at a distance.
6
Print a sheet with both colours, every value and the difference, to take along to the paint shop or the press.
7
Done, or something went wrong? Open the dashboard and start over with a clean sheet.
Reviews will be available soon.
