Adobe Illustrator Vector colors look completely different when opened on another computer


I have sent a file to a client which was saved in CMYK colors. They opened the file and the colors are nothing like the original design. Any ideas what is happening here? Any help is much appreciated.

Bottom line: you can't guarantee a file's colors to look identical on any two screens.

First, CMYK is nothing but an approximation, as long as it's on your screen. RGB and CMYK are so fundamentally different color spaces that it's impossible to display the one in the other, even if you calibrate.

That said, calibration (or lack thereof) are wildly different between different machines. In addition, people have different preferences for their screen settings like brightness, contrast and saturation.

Lastly, if you are talking about a *.pdf files (which I guess you are from the pdf tag), please be warned that most *.pdf viewers are absolutely horrible at displaying color profiles, and more, in print-oriented *.pdfs. If your client uses a different viewer than you are, there's a 99 in 100 chance that color display is off.

Incorporating Gramps's comment, it might be a good idea to inform the client of the fact that only actual printing will give a proper idea of the colours.
