Several skin rarities are available:

Common (gray)

Rare (blue)

Epic (pink)

Legendary (yellow)

Mythic (red)

Unique (turquoise)

The "common" skins are the 2 default skins of the game, the "rare", "epic" and "legendary" skins are available in the shop and in the item crates. The "mythic" skins are very rare and can only be obtained after a game (win or lose), with a lot of luck. The "unique" skins are the rarest skins in the game, there is no way to have them by playing. The only way to get them is to be a "beta tester", have the "founder" pack or be part of the "GG_games" team.

To date there are 57 skins including 3 "unique", 6 "mythic" and 2 "common". The rest are available in the shop.
