Was Brian done painting the pH chart according to Universal Indicator colours? Well, yes, actually. He was. But then the guy was talking more and really he wasn't so bothered and he did say they were welcome to draw ugly things so he'd just continue with chemistry colouring.

Maybe he'd do phenolphtalein indicator now. Yeah. Great idea.

And methyl orange.

He was so good at this drawing circles of colour on his canvas. Oh yeah. Only thing he could draw. He'd animate later. Or never. How do you animate a colour chart anyway?
