Hi Fraser,
Not too bad - well, better than first time around back in September/October - just struggling to concentrate on screens for too long.
The brown is a tricky one, I admit: Precision P39 is called 'bauxite' but is quite brown (I've had a couple of tins over the years - I think Don Rowland used something a bit like that on his LMS wagons from the very occasional colour picture I've seen). Railmatch 612 is much closer to BR Freight Stock Red as generally rendered and is really quite orange in tone. Hornby tinplate and Dublo seem to have pitched somewhere in the middle for what that's worth:

The above borrowed from an eBay listing (for information only). More pertinent, since it shows the real thing is this image which I remembered after I'd applied the paint:
NB - Flickr posted the preview of the image not me: click on the link for a larger version.
That certainly looks very much more like the Precision colour (with all the caveats about scans of 1930s colour film/monitors, etc., taken as read in case
@oldravendale is watching!). I wouldn't like to say which is right or wrong and if I decide I really can't live with it, I can overpaint it. I would value your opinion though.
