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 a rainbow trail, 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

 * Some ships that are hard to unlock, like collecting 500 stars or beating 5 demon difficulty levels can be easily unlocked in the Lite version, such as collecting a small amount of secret coins.
 * However, completing Clutterfunk or Electroman Adventures in normal mode, completing 5 Map Packs, or Completing 100 user created levels are the easiest way to get a ship.
 * Icons that are awarded for easy achievements, like 'Stereo Madness!', are lacking in detail and are not 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 is a total of 47 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. Tap the icons (up to 200) on the main screen to unlock them. Unlocking the second secret will reveal how to get 2 icons and 1 color (the achievements are  'Rampage!', 'Dominating!', 'Godlike!')
 * On the main screen, there are no icons that are travelling in the antigravity, mirror or dual modes.
 * 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 5 new icons.
 * A cube icon which looks like a mushroom from the Super Mario games.
 * At least two new wave icons which feature more intricate designs.
 * In the sneak peek #2 video, it shows an icon that looks similar to Batman.
 * In the sneak peek #1 video, an icon resembling Flipboard-Block from Super Mario World is shown.
 * The icons from Geometry Dash are used from the Oxygene 1 font, like "Stereo Madness!" and "Dry Out!".
 * The "Geometry Dash", "Practice Complete", "New Best!" and the "Level Complete!" texts are also made with the same font.
 * The UFO unlocked for completing 30 map packs is based off of Bowser Jr's ship in Super Mario World.
 * Although there is a lot of normal cube icons, there is only one small form cube icon which is the default one.
 * 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 unlocked 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.
 * All Steam icons can only be obtained in the mobile version if a steam save is ported onto the mobile game. One may port their save where they have completed the 3 levels and Clubstep to obtain these icons and return them to their mobile.
