Xcalib

Xcalib is a command to load a colour profile to your monitor.

Strengths [Weaknesses]

Simple

Xcalib is simple and effective colour management software. It does one thing: adjust the colour profile of your display.

Weaknesses [Strengths]

Simple

Xcalib is a simple command. It adjusts the colour profile of your display, and that's all. If you are looking for a graphical control panel that claims to assist you to find the best gamma level based on your own perception, this is probably not the tool for you.

Install

Install xcalib from http://slackbuilds.org.

Usage

Xcalib has two use-cases:

  • Load a pre-defined colour profile into your display.
  • Adjust the current colour profile of your display.

Load a Colour Profile

To load a colour profile, just invoke xcalib along with the path to your colour profile: 

$ xcalib /usr/share/color/icc/eciRGB_v2_profile-2011/eciRGB_v2_ICCv4.icc

Ideally, you will have created a colour profile for your monitor with a colour calibrator like Color Hug, or else managing colour profiles of your screen is probably not doing much good.

To have this happen automatically upon boot, add that command to your ~/.bash_profile file.
