Well it is said often that since we are visual artists, we will know it when we see it. Here I am at my weeklong course in Haliburton. I have been painting for nearly 2 years on a black textured surface. Since there are paintings that don't seem compatible with the black underpainting, I wanted to see how it would work on a white textured surface. Well , it's AWFUL! so back to black. It is awful because the black lines recede and the white lines come forward. Virtually all colours look luminous on black because they are lighter and brighter. On white , not at all. See for yourself. I didn't spend the time completing the painting but you get the gist of it. I can see that this isn't it!
