Tree bark on tidally locked planets

I saw this video, and I'm curious what color bark would be if the sun was in one position constantly.
The video explains that birch trees are white because of stuff in their bark. The reason is because the sun where birches are usually is only in one direction, but makes a small arc in the sky. The white color helps the tree avoid temperature differences across its surface.
