What are Colourisable Mounts?

Question

With update 12.60 new "Colourisable Mounts" been introduced to the game. What are those and what does it mean?

Answer 1

 The mount Krakoloss is the very first mount colourisable, it means that just like an outfit (same window) you can change the colors of the mount according your preference.

To get this mount you have to defeat the boss Tentugly's Head  during the A Pirate's Tail Quest.
