Purple violet Molotow's Premium spraypaint range. Belton cans come in a huge range of colours and are perfectly opaque, weatherproof, UV-resistant and lightfast. Because they are made with quadruple-ground car paint pigments, Belton colours are exceptionally permanent. German street artists who used Belton cans in the 1990s have reported that their artworks have barely faded or weathered in two decades.
