You can do this by using a repeating CSS background-image inside an
absolutely positioned, absolutely sized div-block.
The image should be a GIF-file consisting of minimun 2 pixel high, 2 pixel
wide, 2 colors. One of the two colors is transparent, the other is the
actual colorizer, and together they make for a chessboard pattern. Now you
can e.g. darken an image by using black.
