Things I might have seen in London, part 10

In colour with a "u", here are some gouache studies which I have been working on over the past couple of weeks. It's a challenge to work in the rain and snow sometimes. Look closely and you can see some rain spots. I learned a very important lesson in the course of working on these: zinc white sucks. I bought a cheap Windsor and Newton gouache set which came with zinc white. This pigment has the unfortunate property of absorbing colour from pigments that are applied on top of it. The solution: use permanent white instead. Permanent white uses titanium dioxide as a pigment base. It's superb, very opaque, and layers quite well.
