Hello!
I’ve got a question about the difference between colors in the CMYK and RGB modus.
A friend of mine is graphic-designer who is very familiar with colorspaces. He told me, that it is hard to convert some colors (e.g. blue) form RGB into CMYK. I didn’t believed him, so he made a picture in PS, totally filled with the RGB-color blue (R=0, G=0, B=255). Then he duplicated the picture and converted the other one in the CMYK-mode. The difference between the two picture was enormous and I wondered. He told me, that there is no program and no easy possibility, with which you can convert the color e.g. blue from the RGB-mode into the CMYK-mode looking the same on the screen. So I believed him, but I couldn’t explain myself, why there is no possibility to convert one color from one space into the other looking the same form the beginning.
The computer and the monitor is using a color management, that has been adjusted by an expert, so this can’t be the reason.
I’m familiar with PS, espacially manipulating photos, but I haven’t found any answers in the web, why there can be so much differences between a color in one space compared to another.
Any explanations?
Greetings
