What is seen on your display and what the image should look like can be two quite different things.
If you value image quality and accuracy, calibration of your monitor will be important. Anyone involved in digital photography, graphic design or artwork will recognize the importance that their monitor is producing the best results, showing true colors and black levels.
The objective when calibrating a monitor is to ensure the monitor has color references known by everyone (humans and software). This will mean the colors are represented accurately on your monitor.
Generally speaking, using a color measurement instrument to calibrate your display will result in a better calibration compared to a visual calibration. The following open source tools are invaluable for anyone looking for accurate color reproduction.
We make the following recommendations captured in a legendary LinuxLinks-style ratings chart.

Let’s explore the monitor calibration tools at hand. For each title we have compiled its own portal page, a full description with an in-depth analysis of its features, together with links to relevant resources.
