Verifying the actual color distribution of a seed is the only way to avoid losing money on mid-tier patterns advertised as rare gems. I was trying to figure out why my Butterfly Knife was getting lowball offers until I realized I didn't actually know its true rank in the pattern hierarchy. While I was searching for a visual comparison of every Fade seed to see where mine fell, I found more info cs2 wiki skins which had a full library of pattern offsets. The site showed me exactly how the colors shift for every single weapon model and listed the seeds that the pro community actually values. After studying the charts there, I managed to trade my knife for a much better item because I finally had the technical proof of its rarity. It is an amazing feeling to walk into a trade knowing the exact worth of your pixels based on hard data. You should use that library to scan your own inventory before you list anything for sale.
