We have loaded a profile created under Windows, is this profile accurate in Linux given that it is not processed the same way as under Windows?

My methodology:

  • I've created the profile under MS Windows
  • loaded under MS Windows and I've measured some color patches with the colorimeter (first line of the results)
  • I've loaded the profile under Linux using Xcalib
  • then I've measured the color patches through the same colorimeter but connected from a second computer (under Windows) with the same software version as used for my first measures. Results are on the second line here.
  • Computed a DeltaE for each color measured to see the... delta.

The results:

white
39.944 / -32.287 / -14.397
40.152 / -32.366 / -14.561
DeltaE: 0.24

grey 90
% 34.923 / -28.010 / -13.397
35.495 / -28.177 / -13.498
DeltaE: 0.57

grey 60
% 22.958 / -18.877 / -8.160
23.678 / -19.231 / -9.119
DeltaE: 0.74

green
30.662 / -39.411 / 31.107
31.093 / -39.668 / 31.262
DeltaE: 0.43

blue
19.102 / -19.473 / -47.003
19.022 / -19.066 / -47.829
DeltaE: 1.51

red
14.134 / 18.997 / 8.038
13.879 / 20.905 / 6.802
DeltaE: 2.84

A DeltaE below 2, a human eye can (almost) not make the difference. Between 1-3, the results are excellent, and here all results are below 3. Given the very small differences involved, my colorimeter is proably not precise enough to be completely reliable from one measure to an other.

If this is of interest for someone, I am ready to post my methodology to provide you with the results above (in perticular computing the DeltaE).
