I decided to knit another one right away. The last one, blue and green, was a bit large, so for this one, I tried a smaller needle size and less number of rows.
The yarn is Madelinetosh Cove (pale blue and pale beige), Sundara Yarn Cactus yellow, and hand-spun red/yellow/green yarn. The last one, sky blue, is Madelinetosh Morning Dove (sky blue and grey).
I learned that you can create gorgeous colors by mixing many colored yarns.
