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.

Verdict

The call

The clearest difference is in-app purchases: NullG TacOps at none against Model Colors's 4. NullG TacOps also leads on review sentiment (86% vs 60%) and iOS requirement (17.6 vs 26.0). Model Colors's advantage is rating (4.6 vs 4.2) and ratings volume (445 vs 34). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Model Colors holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Model Colors has 445 ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 60% of Model Colors's written reviews are positive against 86% of NullG TacOps's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Model Colors ships an update monthly, NullG TacOps every 4 weeks. The most recent releases landed on September 18, 2026 and September 9, 2026 respectively.
