Icon Kit

The Icon Kit is a feature where a player can change their appearance in Geometry Dash. Although there is no physical difference to gameplay, the player can select from a variety of visually appealing options, including icons for the cube, ship, ball, UFO and the special ball all with their own unique looks. Colors can also be applied to make unique creations consisting of a primary and secondary color. However, the two chosen colours remain consistent between all forms, disallowing multiple color schemes.

By completing Achievements, more colors and icons can be obtained.

Trivia

 * Icons that are awarded for easy achievements, like 'Stereo Madness!', are lacking in detail and aren't very intricate. However, very challenging achievements like 'MORE SHINEY!!!' award very detailed icons with intricate patterns. Players can use these icons to show off their accomplishments.
 * The primary color will also be used in the progress bar if turned on.(The default setting is 'off', so it has to be turned to 'on' if the Player wants.)
 * As of Update 1.9, there are a total of 46 cube icons, 24 colors, 18 ship icons, 10 ball icons, 10 UFO icons, and 1 wave icon.
 * Choosing black as the primary color will change what is normally the black outline into the secondary color. Several other changes occur which mostly applies the secondary color to map components in place of the black.
 * Update 1.7 added a special option unlocked by completing 10 map packs, which is a rainbow trail emitted behind the player when contact with jump pads, jump rings, gravity portals, ship, or UFO mode. Contact with size portals, mirror portals, speed portals, and ball portals do not show the rainbow trail.
 * Update 1.7 had a sneak peek picture that featured a ball that never came to game.
 * Cycles and xStep are the only levels where you can get icons both in Normal Mode and Practice Mode.
 * Clubstep is the only level where you can get a UFO in Practice mode and a Secondary Black Color in Normal Mode.
 * The icon unlocked by completing Hexagon Force in Normal Mode is a reference of a Creeper, a popularized enemy creature from the game Minecraft.
 * Update 1.8 added secrets to the game. Unlocking the second secret will reveal how to get 2 icons and 1 color (the achievements are 'Rampage!', 'Dominating!', 'Godlike!')


 * Update 1.9 added a new secret to the game. Upon collecting it, the player will be rewarded with secret coin and new color with achievement "Master Detective". See the Achievements page to find out how to earn it.
 * Update 2.0 will most likely introduce many new icons, but so far the preview pictures have confirmed a few things
 * A cube icon which looks like a mushroom from the Super Mario games (seriously)!
 * At least two new wave icons which feature more intricate designs.
 * The icons from Geometry Dash are used from the Oxygene 1. The icons are 'Stereo Madness!' and 'Dry Out!' and More.
 * The UFO unlocked for completing 30 map packs is based off Bowser's ship in Super Mario World.
 * The Steam exclusive icon for beating 3 main levels is an obvious reference to Valve's Portal-series Companion Cube.
 * The other Steam icon for beating Clubstep (SteamStep!) has special glasses that look exactly like the official Steam logo.
 * Despite only being able to be used in the Steam version of Geometry Dash, the 'SteamStep' icon makes an appearance in the iOS version as an icon in the background on the main menu.
