Been trying and failing to get an answer out of Google for this, so now I'm trying here, but does anyone know when the French changed uniform colours from horizon blue to the green they were using in 1940?

Try this Yahoo group: http://groups.yahoo.com/group/France1940/?yguid=118327779

This thread seems the most relevant: http://groups.yahoo.com/group/France1940/message/8278

Here is a quote from the thread, "Come to think of it though, many (most?) of the helmets must have
been manufactured before the French Army 'went khaki' in the late
1930's and hence have originally been issued in horizon blue."

Hope this helps.

Well, I just did a quick search in french and it seems they changed from blue to khaki in 1935:
From wikipedia: Le bleu horizon est ... utilisée pour les uniformes  de 1915 à 1935, date à laquelle elle est remplacée par le kaki.
Roughly translated as: Horizon blue was used for uniforms from 1915 to 1935, at which date it was replaced by khaki.
Here's a link http://fr.wikipedia.org/wiki/Bleu_horizon

Hope that helps, if you don't trust wikipedia thats fine as I know its not always reliable, but this should be right 
I speak french and english so you can trust my translation.
