libcolord-gtk-dev 0.3.0-3.1 (arm64 binary) in ubuntu mantic

 colord is a system service that makes it easy to manage, install and generate
 colour profiles to accurately colour manage input and output devices.
 .
 This is a GTK+ convenience library for interacting with colord. It is useful
 for both applications which need colour management and applications that wish
 to perform colour calibration.
 .
 This package contains the development files necessary for a GTK+ program
 to build against the libcolord-gtk library.
