The very slightly different color would suggest that Izi's idea about texture filtering
may be the problem. A filtering algorithm often 'backtracks' to fill in the first
dot in the pattern, and the 'backtrack' may be slightly off. (A rounding error, for instance.)
I tried doing a similar render and then scanned around with PSP's color picker and
couldn't find any differences, but that doesn't mean they aren't there in my picture as well.
