I recently purchased a new Acer S201hl monitor. Many lay reviews compliment its color accuracy with people noting only a bit of a blueish tinge.

After a little time, Windows found, and I installed, the Acer drivers via Microsoft Update. During the installation process, the software installed an ICC profile for the monitor from Acer.

I recently noticed that when I view photos using Windows Live Photo Gallery, the colors are wrong. For example, grayscale document scans appear with yellow backgrounds instead of white backgrounds. This happens with both my external monitors and my ThinkPad's built-in screen. When I removed the monitor-specific profile from the list of profiles associated with a monitor (for example, removing the Acer profile from the Acer monitor), the problem went away for that screen.

I checked with Microsoft KB939395 and though it says "an incorrect color profile [...] is used for the monitor," the profile associated with my ThinkPad's screen seemed to be correct, based on its name.
