Recently I pulled out a sketchbook from 5 years ago, intrigued that I had actually stayed with the same limited palette and 2 ink colors throughout the entire book. I could not replicate the colors exactly, as I no longer have a couple of them, but I put together a similar palette for this muted color chart in my current sketchbook.
The thin sketchbook of 140 lb. 100% cotton watercolor paper was a dream to work on! I began it on my birthday; including turquoise was influenced by the turquoise elastic band that came with the book. If I remember right, I even stuck with exactly the supplies shown on the first page!
