WWI Artillery color for 75mm French Cannon

I am in process of building the 75mm QF French Artillery gun used on the Western Front. Does anyone have information on the correct pattern or color used for this piece?

The kit is very old and was probably made in the 70’s. The modeling company was out of NJ. I got the kit at a flee market and decided to build it. It is 1:24 scale (I think). Makes a nice addition, but I am pretty sure not accurate.

Here’s a pic of another artillery piece used in WWI, it’s not a 75mm QF French Artillery gun, but it could still help with a paint scheme.

If you decide you need anymore pics of the howitzer above, just ask.[:)]

I’ve seen several French 75’s over the years, and most are a greenish grey color, but I’ve also seen a couple that were painted in O.D. The one at Ft. Sill was the grey color; if that matters.
