Ime, the Oxbow I've seen is within the realm of natural hay colors. The batches I've gotten in the last 6 mo. were just very stemmy and yellow/brown. The Kaytee I've gotten in the past is consistently a uniform pale green, which anybody that sources their hay locally can tell you is odd. There's always some natural color variation b/c of how much liquid, sugar, etc. is in the grass when it's cut and dried. If every single stalk or stem or leaf is the same color (or nearly so) I'd suspect it to be artificially colored.
