Paint colour of the metal and wood work on District line

[bridge1102]

Hi, We are building a model of West Brompton Station in 7mm in the late 1950's and would be glad if anybody can give an indication of the colours used for the metal and wood work within the overall roof at that time. The only picture that I have found is in 1990 and this indicates it was white/cream with black, currently it is green and red but in 1957....?

Any help gratefully received

London Transport Museum would be the obvious people to ask.
