To paraphrase Shakespeare, “Would a Cheeto by any other color taste as savory?”

In many cases[0][1][2] it's treated with carbon monoxide to make it look redder.

Probably all of them. We are super sensitive to colors.
Red meat and fish like tuna and salmon have carbon monoxide and sodium nitrate treatment just to keep them red because that's how people think they can judge quality.
> Consumers will pay up to $1 per pound more for darker colored salmon compared to salmon with lighter hues, according to research by DSM, a company that supplies pigmenting compounds to the salmon feed industry.
Seriously?
Alternatively, if we stopped dyeing fish, a year later people will have totally recalibrated what they think fresh, healthy fish looks like.
Wild salmon eat krill and other smaller organisms, many of which provide the components to turn the salmon meat a shade of pink.
Farmed salmon don't get the same components in their feed, so their meat isn't the same colour. So the farmers add some of those components into the salmon feed, et voila - pink salmon meat.

There've been ridiculous attempts to get rid of perfectly innocent flavor enhancers before, like the fight against MSG. Take out MSG, and food tastes less good. But take out a borderline red dye, and what's the worst that happens? Factories have to sell soda that's slightly less pretty in the bottle?
