I keep seeing signs about foot high or suspended from platform canopies that have different colour zones on
What are they?
They were (and still are occasionally at Reading for first/ standard class) used to help passengers locate where their coach will be when it arrives.
I don't pay an awful lot of notice but I believe they are Blue, Purple, Gold and Yellow, plus whichever one I have missed.
Ah right, I've noticed ones at Bath are now gone and been replaced with actual coach letters. But Swindon has a couple still on the island.
Here's a blue one since they demolished most of platform 7 (nee 4) at Reading with the new mega structure forming in the background.

Link - It's not very interesting though.
It just takes me to the national rail site, bloody phone lol
As does Preston, IIRC.
Imgur link. It really isn't that interesting although you can tell it used to be P4 since there is no mention of where P4 is
As for the signs I believe Birmingham International ([stn]BHI[/stn]) and Coventry ([stn]COV[/stn]) have them.
Wait in the blue zone for the 0822 to Bedwyn.
There is no parking in the white zone.
I greatly prefer the French system: a display which shows where each carriage will be placed on a given train -
(http://frenchmelbourne.files.wordpress.com/2012/02/04-theme_composition-trains.jpg) the letters along the bottom of the display are the equivalent of the coloured zones occasionally used here
I have seen these at watford, i assumed thats what they was for but never knew which coach its actually related to.
In a slightly off topic would it not be more usefull to have screens dotted down the platform that change depending on the next service ie; Wait here for coach C. Maybe getting ahead of myself lol.
