Now I make a fully calibration with the "color checker x-rite" chart to update
the color setup algorythms. I can say it was a quite succes, now the colors from
interface spot objects or the color checker card are 95% equal to
the macbook LCD. To have the last 5 % I think I have also to calibrate the
LCD display and do fine-tunning.
Soem color conversion
