With the Barbarian Assault improvements update on 19 January 2010, players were given the option of purchasing abyssal whip paint in any of four different colours for a price of 50 honour points each. The whips may be coloured blue, white, green, or yellow, and colouring a whip renders it untradeable and non-lendable. However, the paint may be removed using a cleaning cloth, returning the whip back to normal. On 29 March 2010, the rewards interface was updated so that players could recolour whips indefinitely once the specific colour had been purchased. Prior to this, each time a whip was coloured, 50 honour points were required. Additionally, abyssal vine whips may be coloured just as regular abyssal whips are.
