The attacks are on reduced-round versions of SHA-256 and SHA-512. Those do not describe any attacks faster than (dumb) brute force against SHA-256 or SHA-512.
I think labeling SHA-256 as orange is highly misleading. The SHA-2 family of hashes is going nowhere unless the partial-round attacks get a lot closer to the full-round versions. They're still about 20+ rounds away.
