Beef is treated with carbon monoxide.I am unsure of how big of a deal artificial dyes in beef are.
A cursory google gives a list of natural food dyes used with beef and claims that dying fresh beef is unnecessary / uncommon
I don't know if CO is covered under this order, but I do not like brown beef. Walmart must not treat their beef as it's always brown. I never buy beef from Walmart.

Is Meat Too Red To Be True? | Andrew Weil, M.D.
The use of carbon monoxide treatment is approved by the FDA to keep meat looking red, fresh, and more appealing to consumers. But is this safe?
Beef turns brown by oxidation, hence the introduction of carbon monoxide which replaces the oxygen in the meat.
