                                According to the British Dietetic Association, whole milk is typically indicated by a blue top in the UK, while semi-skimmed is green. However, this color-coding is not universal, and the term "dark blue top milk" can mean different fat contents depending on the country or brand. This lack of standardization is a common source of confusion for consumers everywhere.
