Bottle and Bananas

Our plans for the weekend are put on hold as we head for the hospital to visit a relative (he’s doing much better now). I’ve spent many hours waiting in hospitals but, as usual, I’ve brought my sketchbook and pen with me and this time a tiny pack of crayons. They’re a very limited range, just seven colours, but working out how to represent the range of colours reflected and refracted in the bottle of Harrogate Spa water takes my mind off a worrying situation.
