"FLATS - Background colour" Topic

So I ran out an old scenario last night, an assult on a heavy field gun battery. No way was I going to use 3D minis for a once in 10 year game. I made up some Junior Geneneral flats and it was very effective having only taken minutes to make. However it did occour to me to wounder what the ideal background whould be for the models. White does not seem ideal, should it be grey or a slight blue tint? Anybody done a practical test?

I assume it should be as quick job im many cases in a paint package to do a find and replace colour job to change the baccground.

Light blue or gray should be fine. Easy enough to do a couple of test prints to see which you like.

I usually use black.

As you're going to be looking down at an angle "through" the flats, how about a light earth-green to match your tabletop? (Or whatever color predominates in your terrain, making sure to print a color a bit lighter in tone than the actual terrain so as not to stand out.)
