colord is a system service for managing, installing and generating colour profiles. It provides a central service that applications can use to associate hardware devices with the appropriate ICC colour profiles, helping maintain consistent colour handling across the desktop.
The software runs as a system-activated daemon, starting when a graphical or command-line client needs it rather than running unnecessarily. Applications communicate with the daemon through a D-Bus API, while colord maintains persistent device-to-profile mappings in a database. It can also provide system-wide colour settings that apply across users and sessions.
This is free and open source software.
Key Features
- Maps input and output devices to appropriate colour profiles.
- Provides a D-Bus API for applications and desktop components to query and modify colour-management information.
- Maintains persistent device-to-profile mappings using an SQLite-backed database.
- Supports system-wide colour configuration across users and sessions.
- Manages ICC profiles and uses Little CMS for colour-management functionality.
- Includes the colormgr command-line utility for viewing and changing devices, profiles and their associations.
- Creates and removes devices and profiles from the command line.
- Assigns profiles to devices and selects default profiles.
- Finds devices and profiles using identifiers and properties.
- Includes cd-create-profile for creating ICC profiles, including named-colour profiles generated from CSV data.
- Includes cd-fix-profile for modifying ICC profile metadata and repairing common profile errors.
- Supports colour-measurement hardware through GUsb.
- Offers optional integration with ArgyllCMS colour sensors.
- Provides optional SANE integration for scanners.
- Integrates with desktop colour-management software such as GNOME Color Manager.
- Uses system activation so the daemon is started when colour-management services are required.
