# Customizing annotation color pickers on iOS

There are a couple of places in Nutrient that open a color picker to let the user choose, for example, which color an annotation should be drawn in. Whenever possible, Nutrient uses the UIKit-provided `UIColorPickerViewController`, which ensures a consistent user interface across apps and provides a familiar user experience. `UIColorPickerViewController` provides three different palettes to select custom colors: a color grid, a color spectrum, and RGB sliders. Additionally, an extremely useful eye dropper tool is also available to sample colors from any part of the screen.![Standard UIKit Color Picker](@/assets/guides/ios/customizing-the-interface/custom-color-picker/color-picker-uikit-component.png)

## Legacy color picker

Nutrient uses a legacy color picker in apps built with Mac Catalyst, because the system-provided color picker is limited and offers an inadequate user experience compared to the color picker on iOS.

Customizing the legacy color picker has no effect on the UIKit-provided color picker. The legacy color picker is deprecated and will be removed in the future.![Legacy PSPDFKit Color Picker](@/assets/guides/ios/customizing-the-interface/custom-color-picker/color-picker-pspdf-component.png)
