I have recently started really studying the plastic blank color combinations. It seems to me, after pouring almost my entire first gallon of equal two color combos, that the really cool blanks are very lopsided when it comes to color amounts. It seems there is always quite a bit of one color, and just a little bit of another color or two. I have a pour right now in the oven that i have started experimenting with this phenomenom, and plan to do another pour even more lopsided. We will see what happens.
