The link provides more of a tutorial than a pattern, because it relies so heavily on a specific type of yarn that may not be widely available.

After shopping at a professional dyer’s studio on vacation this summer, I walked away in possession of two skeins of yarn with sharp contrast: deep blues to lime green, and bright pinks to yellows. For me it was an unusual choice, but an idea occurred to me. What if you use a particular stitch to deliberately pool the colors and highlight certain shades?

The colors of the blue-to-green skein put me in mind of Monet’s Nymphéas series of paintings - you know, the ones with the water lilies. From this concept, I created the Monet Mitts.
