Icon Kit

The Icon Kit is a feature where players 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, wave, robot and assorted trails, 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 colors remain consistent between all forms, stopping you from having multiple color schemes.

By completing achievements, more colors and icons can be obtained. As of  Update 2.01, there is a total of 64 cube icons, 28 colors, 25 ship icons, 18 ball icons, 18 UFO icons, 13 wave icons, 6 robot icons and 4 trails.

The words inside the parentheses is the achievement name for each icon. Unless marked as such, these icons are not available in Meltdown. Do note that some icons may have different requirements for getting them in Lite. Cubes=

Trails
A trail may sometimes follow behind the icon. This occurs at different times and is dependent on the form and its interactions with map components such as pads, rings, and portals. Update 1.7 introduced the first unlockable trail that additionally enabled a 'Glow' option that formed an outline of the selected secondary colour around the icon. Update 2.0 changed it so that unlocking the rainbow trail would provide the ability to enable and disable the Glow option individually, no matter what trail the player is using.

An unrelated trail with ghosted copies of the player is activated at different times during levels, and is also a feature available in the level editor. This feature was introduced in Polargeist (The Seven Seas in Meltdown). The trail uses only the icon's color 1 details.

Trivia

 * Icons that are awarded for easy achievements, like 'Stereo Madness!', are lacking in detail and are not very intricate. However, very challenging achievements like "Demon Master" award very detailed icons with intricate patterns. Players can use these icons to show off their accomplishments.
 * The most detailed icons are the Cycles icon, 400 stars icon, 900 stars icon, the Icon rewarded for beating 4 demon levels, and the icon rewarded for completing Deadlocked in normal mode with all 3 coins.
 * The most detailed ships are the 30 and 80 user coins ships, the 600 stars ship, the 115 and 90 secret coins ships, and the 1000 user levels ship.
 * The most detailed balls are the 70 secret coins ball, 190 user coin ball, the ball for 40 map packs, and the ball unlocked for getting 2000 stars.
 * The most detailed UFOs are the 45 secret coins UFO, the 65 secret coins UFO - This is because of the robot-looking hands that are small but also detailed- and the UFO unlocked for beating Clubstep with all 3 coins.
 * The most detailed waves are the 120 and 170 user coin waves, the 4000 stars wave, and the wave that is unlocked by typing "Ahead" into the Vault.
 * The most detailed robots are the robot unlocked for completing Deadlocked in normal mode the robot for completing Geometrical Dominator, and the robot unlocked by collecting 100 user coins.
 * The most widely-used icon is the icon awarded for acquiring 300 stars (used by many famous players such as GuitarHeroStyles/AdvyStyles and Tama_N due to its 3D appearance when colored correctly).
 * The icons incoming in update 2.1 are referencing characters from Robert Topala's previous game called Boomlings.
 * No matter what primary color the cube is, the Lenny Face icon's eye borders, and the rest of the face will be black. This can result in an icon with nothing but 2 eyes if primary black is used.
 * The primary color will also be used in the progress bar if turned on.
 * Choosing black as the primary color will automatically add a glow around the player's icon, regardless of whether or not you have the "glow" option. Several other changes occur which mostly applies the secondary color to map components in place of the black.
 * If both icon colors are set to black, the default decoration color is white.


 * Despite only being able to be unlocked in the Steam version of Geometry Dash, the "SteamStep!" and the "Steamrolling" icons appear traveling across the menu in the mobile versions of the game. The icons can also be acquired in the said versions by loading a Steam-created save.
 * Some ships that are relatively hard to unlock in the full version are easy to unlock in the lite version of the game. For example, the ship unlocked for collecting 600 stars can now be acquired with 15 secret coins.
 * Before  Update 1.4, there has been a shading for the secondary colour and was only able to acquire the primary colour.
 * Update 1.7 had a sneak peek picture that featured a ball which was never released in the actual game.
 * In 2.0, the wave's name was changed to "dart." After many players showed their disapproval, it was changed back to "wave" in 2.01.
 * Prior to Update 2.01, two icons, which are "Nice shot!" and "Catch 'em all!", were glitched and almost impossible to get.
 * Despite being glitched, RobTop used the "Nice Shot!" icon in the first sneak peek video for Update 2.0, where he shows the start of the 2.0 level "Geometrical Dominator".
 * It was possible to get the "Catch 'em all!" icon by tapping a glitched normal-sized mini icon on the main menu. However, there is a rare chance of this happening.
 * The 100 user coins robot's foot's glow is glitched, because it is using the the glow of the robot awarded to complete "Deadlocked" in Normal Mode.
 * The UFO awarded for collecting 85 Secret Coins appears to bear the face of the cube awarded for destroying 200 players on the Main Menu, being the feline-like face.
