I get challenge by dark colours. I cant define the true colour in low light. I thought this was a brown coffee cup until I took it to wash it and realised that it was green. Therefore the two tone effect. Nespresso #6 at Betty’s place. Soy milk. Makes me feel like a coffee right now. This is my first watercolour wash with the set Erin recommended. They are easy to work with. Except when you are dark colour blind!
