I think it might have something to do with what is described. Using your example, I read the first as a big wall, that is the colour brown, made of brick. The second one, I read a big wall, of brick brown colour (brick describing the colour)
They provide different info- on the second sentence, I lost the info that the wall is actually made of brick.
