I looked up Tillamook, first reaction was that it doesn't even look like cheddar - but then I noticed the 'Maker's Reserve White Cheddar'. Why is artificially coloured the default?! 'white cheddar' makes it sound weird/fake/some strange variant, when all it is is that they haven't added colouring to ingredients list.
The non-'white' ones look like red leicester, which is a bit like a mild not very salty cheddar, and that colour.
