Calibrize is a freeware application that calibrates your monitor with you. I am not saying for you, because any calibration application requires you to provide a certain degree of feedback. Once installed, the application will ask you to follow a simple, three-step procedure that will set the monitor to a reliable color profile, so that the colors match certain standards. I recently was needing an application like this, but I couldn't find any. Now, I tried it with my manually-calibrated monitor, and it worked considerably well. However, it is up to you to provide good feedback for the application to set your colors. Once you do carry out the procedure, the application will make sure that colors look the way you want them to look throughout your system. You shouldn't really have any mismatching colors laying around. The application has pretty few guidelines on how to get the product to achieve the best results, but once you figure it out, this could be of considerable help. It is also free.
