Where does color end

and shape begin?  The question folds into itself (as all questions do). Who shapes who:  color or shape?  Shape or color?  Or are they in cahoots.  Cahoots, another word for collaboration?

With writing is it the pen or the paper which brings shape and color to words?  And always, let's return to food.  Here squash and a slab of slate collaboraing with color.  Or the other way around?

And, yes, the collaboration with the app, Circular.
