In painting class at college (NMIT) we have been talking about colour, well our teacher Geoff has.
He introduced us to to Faber Birren as an expert on colour theory.
In particular different schemes within a painting which emphasise different arrangements/compositions and the use of colour.
So I had a crack at a sample from each:
1. Accenting white
2. Achromatic scheme
3. Colour in a darker scheme
4. Colour in a lighter scheme
5. Tonal scheme
