HISTORY OF FENDER COLOURS
These colours were very famous and were used by car manufacturers in the 1950s and 1960s.
Fender obtained the agreement of these manufacturers to use the names of these colours in order to broaden the range of colours available in the catalogue because there were many shades to choose since these colours were a selling point.
Automotive paints were well suited to an industrial environment, easy to apply and with quick drying, they were easy to obtain.
