If anyone's interested I made a program that mapped each pixel to an ASN, and counted how many evils each ASN has. It's available as
a CSV file. The first column is the ASN, the other columns are the number of pixels for that particular color. The (n+1)th column correspond to nth color listed by theymos. (ie. the second column corresponds to the number of black pixels and the 8th column corresponds to the number of pink pixels for a particular ASN).
edit:
forgot to mention that in some cases, a pixel (/24 subnet) correspond to multiple ASNs, or that an ASN is only responsible for part of a /24. In those cases, the color count is incremented proportionally to the size of the subnet they control. So if a ASN controls 10.0.0.0/26, and the corresponding pixel color is white, then the 3rd column (the column for white) for that ASN will be incremented by 0.25, since a /26 subnet is quarter of the size of a /24.
