colord.conf is the primary configuration file for the colord system service, which manages color profiles and devices on Linux systems, particularly in GNOME environments. It allows administrators to customize color management behavior, such as disabling automatic ICC profile generation or limiting device handling.

Located at /etc/colord.conf, the file uses a simple INI-style format with sections like [colord] for daemon settings and [Match] for device-specific rules. Changes require restarting the colord service via systemctl restart colord.

Colord handles colorimeters, printers, and displays, ensuring accurate color reproduction by applying ICC profiles. This config fine-tunes its operation, balancing automation with manual control for professional workflows. Override files can be placed in /etc/colord/colord.conf.d/ for modular management.

Changes require systemctl restart colord; invalid configs may prevent service start. User overrides limited to Scope=user.
