Offering zero camouflage value, the Inferno paint is only famous among some of the players of Tanki X because of its "cool" (word play intended) appearance.
In fact, by using this paint, you may actually be advertising your presence to all nearby or far away tanks. It's almost like putting a huge, flashing neon-colored "attack me!" arrow sign on your tank. Therefore, this paint might serve as a good distraction for enemy tanks while your teammate scurries away with the flag.
That said, the iconic fiery patterns on the Inferno paint is perhaps the major selling point of the paint itself rather than the palette of brighter colors it uses. Players may feel that the Inferno paint displays their fiery passion for Tanki X and would be willing to spend a King's ransom (I'm not joking - it costs 2000 diamonds) just to buy it.
