Chapter 1 - my first colour wheel

Here's my first attempt at a colour wheel. I used gouache
 but had a limited range of primary colours. The results are
 interesting. My yellow and blue were too 'acidic' I feel and
 have produced somewhat muddy secondaries. Am off to
 town now to get some new primaries. Will repeat exercise
and contrast results. Stars and crosses coming on nicely
 will post them tomorrow.
