Mark Carver was thinking very hard :
Well yes, but they seem to be trapped in a negative spiral. I see loads of
white meters in walls, and think a brown one
would look so much better. I'd say probably in the majority of cases brown is
better, but few get fitted because they are expensive !

Anyway, I don't care, I've ordered a brown one.

Nowt to stop you painting them any colour you like, along with any
surface pipes, my two are a rich red.
