David Brown 850

My name is Gerard Leenders from The Netherlands. I just bought a David Brown 850 (serial number 303876, 1960-61, first series). Now I'm looking for the original colours red and yellow. I found on the internet DB Hunting Pink (Cherry) BS538 1939-1962

DB Red (Currant red) BS539 1962-1965 (950 on) DB Primerose Yellow BS310 1958-1965 (wheel centres)

DB Highway Yellow BS356 1960-1988

Which one is the red and yellow I need?
And: the paintnumbers are British standard numbers and several paint shops in Holland (specified in tractors) cannot find the equivalent of Dutch numbers. Can you help me?
Or is there a possibility to order in a shop or by internet the red and yellow colours in the UK?

Many thanks for helping me.
