David Hockney: a lovely example of the Fire element

I have just watched a warm interview with David Hockney, the painter, on BBC television, and smiled throughout.  I wonder whether it is only a Fire person who could paint such delightfully joyous paintings, with their ridiculous-seeming purple trunks and bright red branches. Somehow he even manages to make winter a joyous season.

Somewhat flippantly, this has made me wonder whether we can indeed diagnose artists through their artistic creations.  I doubt, for example, whether a Metal person could see nature in the prime colours Hockney does, preferring instead, I would think, subtler autumnal shadings.
