Tree Trunk Color?

[CRL]

Depending on your climate, they may be green or gray-green, due to lichen and moss.

Yeah, but only on the north side of the trunk.

Yeah, but only on the north side of the trunk.

Actually, I have a number of trees that are green all the way 'round.

So I've used a couple of different options.

In fact, most of my trees are all a blend of various colors.

I start with a gray primer as the base coat.
Then I hit them with a mist of some medium brown.
Then a darker gray primer if everything looks too light.
Finally I'll sometimes mist on a bit of red oxide around the edges.

However, I've also found that Valspar's Treetrunk color does a pretty good job in there too so I've taken to throwing that in the mix too.

try Rustoleum London Gray......it's a grayish brown, or a brownish gray..

I generally paint my trees and armatures with an airbrush. I am using Super tree material. I use three shades of green and paint the leafy area first. Russian Primer, Pale green on top for highlights and an alternate green to add depth. For the trunks I then use a brown first (ammo tracks primer), then use a grey black over the top lightly (Ammo Rubber Tires).
I paint through the foliage keeping the airbrush close to the trunk to paint the upper trunk. I will then dry brush with a light grey to add texture if I use the tree as is, or it will get broken up and used on a larger sage brush armature for a feature tree

I've learned to go lighter gray than what you think.

I think the perceived color can vary depending on the conditions.  If you are modeling winter with less foliage, then the trunks will look more gray.  If the trees have leaves, then the trunks tend to be in the shade and will appear darker and maybe a little more brown.

Not to be a smart a$$, but isn’t it kind of like “what color do I use to paint a boxcar”?
Maybe it depends on boxcar? Just saying..
