an object that can be drawn in a frame
A drawable is an abstract object that can be drawn in a frame. A drawable knows the frame the location (anchor point) within this it has has has a forgeground and background color and a (line) width. What these properties exactly mean depends on the specific drawable.
A drawable contains two colors and one integer. It has a reference to a frame. This frame must still exist when the drwabale is asked to draw itself.
