I have kits and yarn for this pattern in stock in my shop:
Three Birds Yarn Studio

The adult size ‘Chromatic Beanie’ is a bulky weight hat that uses 3 colors of yarn to create a fun and engaging stranded colorwork project. I fell in love with the entire color collection of Wool and the Gang Alpachino Merino yarn; I just knew I had to put a colorwork pattern together. The solid color options range from earthy neutrals to neons. And since they all pair well together, the hardest part is narrowing it down to just 3. One suggestion I have is to pick contrasting colors. I like to pick a light color for color C.
