Hi, I'm trying to make a boundary wall using the patch command for a project. Trouble is while the boundary wall is alright, it's color is'nt what I desired and for some reason the patch command is'nt following the rgb color chart despite what the help on matlab says. I want it to be black. Could someone tell me what mistake I'm making in my code, and tell me how to get any desired color using the patch command? Attsached are the screen shots of my code as well as the resulting boundary wall.
