One evening - tulips from life and trying to figure some limited palette color combos from photos.
Tulips took quite some time. I was trying to use all my low-quality leftover paints before the shipment with fresh colors arrived and yellow was just not working in mixes - mostly disappeared or made mixes dirty. I ended up re-painting greens several times, lost the light and patience in the process. Ordered some new yellow right after this experience.
What are your favorite green mixes?
