Nope. Depends on the cows' diet. Grass fed cows have yellower cream from the carotene. American cows have to be fed on silage for at least part of the year (no grass available!) Also it varies by breed, Holstein (Friesian) cows have white cream and Jerseys are yellow. Sorry :-)

Bizarrely, even though North American butter is normally light coloured, Quebec still has a law saying margarine has to be white so it won't be confused with butter! Margarine is normally coloured really yellow in North America.
