Customisation is a way of cosmetically modifying the player's form in Geometry Dash. Although there is no physical difference to gameplay, the player can select from a variety of visually appealing options, including the cube, ship, ball and UFO all with their own unique icons. Colours can also be applied to make unique creations consisting of a primary and secondary colour. However, the two chosen colours remain consistent between all forms, disallowing multiple colour schemes.
By completing Achievements, more colours and icons can be obtained.
