These are not traces of the background. These are the actual colors of
the pixels. If the edge of red sphere on a blue background takes only
10% of a pixel, then this pixel will have a color of <0.1,0,0.9> . If
you make it <1,0,0>, antialiasing will be totally useless as no
jaggies will be reduced.

I only used it as an example.
