In addition to the full pattern being in the Instagram post, this pattern is also currently available on the Knit Picks blog: https://blog.knitpicks.com/pop-hats/ and it will eventually be on the Knit Picks website as a PDF download.

Make the most of Swish Pops’ many colors in this planned pooling hat! Planned pooling means working the yarn at a gauge and stitch count that causes the colors to line up with each other in an intentional-looking pattern. Depending on the colorway used and the exact gauge, this may be a wavy design, or it may resemble argyle or plaid, or it may be more of a color-block abstract painting kind of vibe. There’s no way to know what you’ll get until you start knitting!
