Sometimes plane color is different what is the reason?
It is because of display settings for planes. But what makes a difference for you?
When I activate sketch command to select a plane, many times I get shaded planes, sometimes I get unshaded planes even though my Display Shaded Planes is check marked.
You get shaded planes as SW wants you to select the plane to start the sketch on.
When I get unshaded planes, I repeat the procedure again to get shaded planes. I can understand now it is unnecessary to do so because it is not going to affect the end result.
Great, now you understood finally
If you'll select a plane first, then activate the Sketch command, that won't happen.
