# NSAppIconComplementingColorNames The names of the colors to use for the background of the App Shortcuts platter. ## Discussion By default, the system chooses an appropriate background color for the App Shortcuts platter — a view that represents a single group of App Shortcuts. You can override that behavior in one of two ways: 1. Specify the name of a single custom color in your app’s asset catalog to show a solid background. 2. Specify the names of two custom colors to show a gradient background. > Important: > Use `array` for the value’s type, even when specifying a single custom color for a solid background. ```swift CFBundlePrimaryIcon NSAppIconActionTintColorName CustomTintColor NSAppIconComplementingColorNames BackgroundGradientColor1 BackgroundGradientColor2 ``` If your app provides multiple app icons, you can specify different background colors to match each alternative. ```swift CFBundlePrimaryIcon NSAppIconActionTintColorName CustomTintColor NSAppIconComplementingColorNames BackgroundGradientColor1 BackgroundGradientColor2 CFBundleAlternateIcons MyAlternateIcon NSAppIconActionTintColorName AlternateCustomTintColor NSAppIconComplementingColorNames AlternateBackgroundGradientColor1 AlternateBackgroundGradientColor2 ``` --- Copyright © 2026 Apple Inc.
