“The experienced painter hops around the palette taking a little of this and layering it on top of a little of that without a thought for what the pigment is called. This is what you should aim for, practicing with your colors so that you know them well is the way to achieve it. Bear in mind that, however many ground rules you learn, every artist develops their own technique, finding by trial and error what is best for them.”
The Art of Botanical Painting, Margaret Stevens
