If the appearance of Kodi looks boring to you, you might want to change it. You can change the colors of its interface, the background image or the way the icons are arranged. This and much more can be done easily by changing your current skin.
The default skin of Kodi since Kodi 17 (Krypton) is called Estuary and it is quite popular among the users, but you can change it and choose between the many skins which are available. Every one of them has its own look and feel including colors, fonts, zoom and additional configuration.
