Model Colors is an application for helping you keep track of your hobby model colors and projects. Have you ever ended up buying the wrong colors because you didn’t remember the exact code of the color you needed or forgot to get that pesky Dunkelgelb that you needed to finish that glorious tank you’re working on? If so, then Model Colors helps you keep track of the colors that you own and the colors that you need to buy. The application contains lists of all colors from a set of brands and you can browse these lists and mark the ones you already own and the ones you need to buy. Currently the app has over 50000 colors included from most big and many small manufacturers. The lists of your own colors and colors that you need to buy can be easily shared via mail, iMessage etc. If you mainly use some particular color types or individual colors you can set them as favorites and easily access them from the main menu. You can check for colors that are similar to a certain color either via color standards like FS, RAL, RLM etc, or via industry standard CIE deltaE 2000 calculations. Various colors can also be grouped together for quick access into custom color lists. You can keep the colors you normally use for US airplanes in one list and colors you use for fantasy miniatures in another, making them easy to find.
