Supra Swatch Colors

Takes 5 to 10 minutes to understand how it works, from then it's super easy to customize it. And I think this is definitely the best swatch/color picker for the price, there are enough other apps that do about the same, but most are $10 a month or even more, just to be able to have a few swatches, I find $10+ way too expensive. Fortunately this one has a great price, only $4 a month (At the moment at least), I am happy to pay this every month :)
