RAL 1021
Colza Yellow
RAL 1021 Colza Yellow is a bright, saturated yellow named after the colza (rapeseed) flower. This is one of the most culturally significant colors in the RAL system — it represents the gold stripe in the German flag and was the official color of the Austrian Post (Österreichische Post) and Deutsche Bundespost from 1972 to 1980. Colza Yellow carries strong associations with communication, reliability, and national identity. It remains widely used in postal services, public infrastructure, and civic signage.
