Try using the sRGB Color Space Profile. You can activate it for almost any graphics card (under windows: right click on desktop, properties, settings tab, advanced button, color management) and you can activate it in good applications like Photoshop etc. This profile is a good "average" for monitor perception and color reproduction.
If your monitor supports sRGB by Hardware, you're on the lucky side. If not, get a standard monitor calibration tool and calibrate your monitor after setting the profile. Matrox and Nvidia cards provide that tool, I think ATI does, too.
It is always a good Idea to use color color management for color dependent design.
