Right, I've managed to write a named color profile using lcms that conforms to the ICC spec. I've not yet managed to read the data out of it tho. I've attached a test file and test wrapper. Compile and run with: gcc -o test test.c -llcms2 && ./test ./x11-colors.icc This produces for me: LCMS error 13: Couldn't link the profiles no transform I can't seem to get named colors to work at all. Ideas welcome. Thanks! Richard.

printf ("no file\n");
goto out;

nc_profile = cmsOpenProfileFromFile (argv[1], "r");
xyz_profile = cmsCreateXYZProfile ();
xform = cmsCreateTransform (nc_profile, TYPE_NAMED_COLOR_INDEX,
xyz_profile, TYPE_XYZ_DBL,
INTENT_ABSOLUTE_COLORIMETRIC, 0);
if (xform == NULL) {
printf ("no transform\n");
goto out;
}
/* retrieve named color list from transform */
nc2 = cmsGetNamedColorList (xform);
if (nc2 == NULL) {
printf ("no named color list\n");
goto out;
}
printf ("SUCCESS!");
out:
return 1;
