# Color devices

Manage the color profiles assigned to displays, printers, scanners, and cameras.

## Overview

Overview ColorSync tracks the color devices attached to the system and the profiles assigned to each. Register a device, enumerate its profiles, and read or set the factory and custom profiles that describe how it reproduces color. Displays are a color device too: you can find a display’s profile from its display ID and read its gamma and transfer tables. Device profiles are themselves ColorSyncProfile objects. See Color profiles.
