Brother-in-law gave me a chunk of fresh yellowfin a couple weeks ago. It was caught on a Saturday and refrigerated for two days when I received it. I cut it into steaks, ate some nice fresh pink tuna steaks that night, and bagged the rest and put it in the freezer (that was around 2 weeks ago). Took a bag out two days ago, yesterday it was still half frozen, then today I pulled it out to cook. Now it's brown all around the edges. I know the stuff in the stores is "artificially" made more red to make it look more appealing, so is this normal?

Yellowfin discolors pretty quickly once you cut it. Grocery store stuff uses artificial coloring as you stated.

this is what you get with frozen tuna and no preservatives.

This is why I eat as much as i can when I have it and give the rest away. I have a loin in my freezer and I can't bring myself to defrost it because I know it's gonna suck.

Was it vaccum sealed or just frozen in water?

Meat normally oxidizes when exposed to air which makes it brown. The store meat is packaged with gas mixtures to prevent the oxidation and keep the red color.
