(FYI all butter is also tinted yellow) This is trivially false, in that even in the US there are many brands that do not color their butter[1], but I'd be interested in knowing the truth. Is there an FDA rule that allows coloring to be added to butter without adding it to the ingredient list? I found a rule saying that FD&C Yellow No. 5 must explicitly be listed[2], and I did not see any exceptions for carotene.
