Your example (pure red and pure blue next to eachother) was silly. That was my point. It is not true that only black and white images show more defined pixels, and colour images do not.
Here the Nikon D200 as example:

Quite interesting link. However unless we're looking into completely different pictures, I can see lots of examples that show nice and sharp black-to-white transitions and really, really bad rendering of colour edges with lots of ugly interpolation artefacts. That red speedometer needle is the best example imho - tack sharp black numbers and ragged red needle. As I can't see similar issues with Sigma's pictures, I'd say this link illustrates my point perfectly.
