Small icon colors

hi

i recently purchased a laptop with Win 8 (64bit) all drivers installed. but in the start menu when i type something to search, the search result icon seems to have color issues. big icons color is perfect only small icon has color issue. please refer attached screenshot

any idea?

That might be not windows 8, but startw8 issue, try some other start menu program, like classic shell, go to settings, find option to make icons small, and see if problem is still here.
