With JPEG, that would result in, a possibly highly contrasting, 
background colour bleeding through on some pixels up to 16 away from the 
intended boundary.  That's because DCT artifacts are spread over 8 by 8 
pixel squares and because the chrominance components in default JPEG 
files are spatially sub-sampled by a factor of two.
