How we built this list

Pattern seeds shown here come from two sources. Case Hardened blue gems are computed by counting blue pixels on each paint-seed render (chescos's open-source dataset — algorithmic, not editorial). The non-CH lists (Fire & Ice, Fade 100%, Crimson Web) are hand-curated from seeds that appear identically across at least two independent community guides (csgoskins.gg, pricempire.com, profilerr.net, steamanalyst.com, bitskins.com, skin.land, etc.). No site's full curated ranking is reproduced.

Want to look up the pattern on a specific skin you own? Paste the inspect link into our inspect tool — it decodes the paint seed locally in your browser and flags it against the rare-pattern DB.
