Again, I'm inspired by Anne-Laure Jacquart (Following the White Rabbit on YouTube), and her tips on greens!
In particular, I was reminded to use a warm yellow like Quinacridone gold (I got rid of Mayan yellow in my palette - it lacked punch for me), and most of all, to use Perylene Green for my darks.
Here are thumbnails and colour swatches. What I'm realising in retrospect is that the paper in this book that I use for trying out ideas behaves very differently from watercolour paper. It's a Strathmore sketchbook I think, and the paint always seems brighter on it than on watercolour paper.
And a few small paintings to try out different ideas. Some worked out. Most didn't!
Blobs of paint. Ugly.
