Green

root@tediore-db:~$ cat description.txt

A Tediore SMG with a fixed corrosive Maliwan barrel, giving it stronger elemental output and damage over time than a typical weapon of its rarity. Because its parts are locked in, it drops less often than its color suggests, but it can still carry you surprisingly well while leveling.

Other Tediore SMGs in this set are Chaff for slag, Kindle for incendiary, and Spark for shock. It only appears at green rarity or higher and is a world drop from suitable loot sources.
