Is it possible that the monitor you are using is the problem? Is it LCD or CRT? Do you have a degauss button? Are your RGB settings correct? On my CRT by selecting different settings, I do get a yellowish tinge in some cases. Also on the LCD, I get the same. Have you tried a different monitor? Perhaps the monitor is on its last legs. What is the manufacturer and model of your monitor?
Another thought that may help. If you look at the Settings tab of the Display Properties of your desktop, is the screen resolution correct. Also is the color quality set to at least Medium (16 bit) color or Highest (32 bit) color. If it's less than this, you may get the yellowish overtone. I just VPNed into a client and saw the same effect because the color quality was set to 256.
Hope this helps to resolve your problem
Would you mind providing us with a little more information about the system you're using. Sounds like a PC. What kind of computer do you have... Are you running Vista, XP, etc. What kind of monitor are you using? And finally, have you checked your monitor settings?
We should be able to do a better job troubleshooting with that info.

Has a solution been found for this problem? I am seeing the same issue in CS4 Photoshop and Illustrator on Windows XP. I have tried setting different color profiles in Photoshop, Illustrator, and Bridge but still see the same yellow tint in the Kuler palette.
