That was my point really - using the sign colour as evidence of the
highway type to dictate the value of the highway tag is good. Recording
the sign colour as information in it's own right with a signage=green
tag is silly.

In other words, it isn't the sign colour you should be recording, it's 
whether road is a primary A road or not. The sign colour just happens
to be one way of determining that.
