I have found myself attracted to bold colours, so I would have to say that I am a colourist. The subject matter is not that important, but I am drawn to scenes from nature; in particular landscapes.
I enjoy taking colours that may exist in a scene and push those colours to emphasis them, and then add the complementary colour for contrast, that makes for more interesting pictures. I wish to build the scene with values and then play with the colours to create the mood that it is desired to convey.
I still have lots to learn, maybe when I am 80 I will get close to understanding painting better.
