During a workshop of the master of packaging at ELISAVA (Barcelona), we have to redesign the pack for a famous american butter (Parkay). This product has to be for mass consumption in supermarkets. We think in colors that usually are used to represent butter. The most common are: yellow, blue and green. This colors represent naturalness, freshness, etc.. We use for natural butter container yellow, to represent a sunset or dawn. We also put cows to represent that the butter contain real milk. We put them grazing in green fields to represent freshness. In the light butter we put blue, that represent a clear sky (softness) first hours of the day. So in both there are happy cows that produce good milk to produce an extraordinary butter.
