Many traditional high quality English and French cheeses have been historically flavoured with additives that also dye them. It isn’t something only people ignorant of cheese do.
I am aware of that. I wasn't implying anything about the relative qualities of different kinds of cheese - just that "all cheese is orange" is a very USA-centric thing. (I suspect it's also a regional thing. Cheddar isn't orange in every state right?)
At every grocery store in the US where I've ever checked, they sell both "white" (off-white) and "yellow" (yellow/orange) cheddar. Yellow is more popular.
They also sell colby, which is a type of cheddar, also usually yellow.
What is regional in the US is the shape of sticks of butter! It's either "Eastern-pack" or "Western-pack" depending on which side of the Rocky Mountains. See https://en.wikipedia.org/wiki/Butter#United_States
Since the Rocky Mountains are the continental divide, that means you can stand in a spot where rain the falls to one side of you ends up in the Pacific Ocean and on its way passes by sticks of butter in one shape, and rain that falls on your other side ends up in the Atlantic Ocean and passes by differently shaped sticks of butter on its way.
I’m in MN (not quite Wisconsin but we love our cheese too) and there’s a ton of cheddar both white and orange. Pretty much any cheddar producer up here that makes orange would also make white. I don’t think it’s as ubiquitous as you’d expect.
