In the
United Kingdom, milk has been traditionally marketed and labelled as follows since being proposed by John Morris of the
British Retail Consortium in 1998, which based the colours on
Marks & Spencer cream packaging (blue for double cream, green for crème fraîche and red for single cream): • Whole milk (around 3–4% fat) – Plastic bottles marketed in blue packaging. • Semi-skimmed milk (around 1.8% fat) – Plastic bottles are marketed in green packaging. • Skimmed milk (around 0.1% fat) – Plastic bottles are marketed in red packaging. •
Channel Island milk (around 5–5.5% fat) Often referred to as gold top, although this varies. In the UK, milk is sometimes still delivered on the doorsteps by a
milkman in the early hours of the morning in glass pint bottles with the colour printed foil lid indicating the milkfat content. Whole milk had plain silver foil, semi-skimmed milk had silver foil with red stripes and skimmed milk silver foil with a blue checker pattern. • Whole milk is 3.5% fat • 2% Reduced-fat milk • 1% Lowfat milk • 0% Non-fat milk (also called skim milk or fat-free milk) United States milk producers also use a color-coding system to identify milk types, usually with the bottle cap or colored accents on the packaging. Whole milk is often denoted by red, while 2% is most often colored blue. 1% and skim colors vary by region or dairy, with common colors for these lines being purple, green, yellow, pink, or light blue. ==Production==
