This is black and white only at the moment brush sizes 1-20 to clear change the "clear" variable to two then it will change back to 1 and clear the screen with the pen on feature you have to set it to 2 to draw this feature was put it to prevent mistakes while rendering but you have to set pen on to 1 to turn it before rendering if you don't want to make mistakes while rendering
