This all sounds interesting but I have 0 clue about what the author is talking about. Can somebody explain what is being talked about, what color calibration is and all? Not a designer, but a systems programmer. I do understand rgb, hsv colors but that's it.

The author cries about being not able to boot from the USB stick and that his ColorHug2 might be broken.

If you do any professional color work, you want a color calibrated display. This ensures that the colors you see on your screen will be the same as the ones on your designer colleague’s screen, and the same as the ones that come out of the printer’s factory, for instance.

Higher end displays are already pretty decently calibrated out of the factory, but if you want to be exact you will need to buy an external piece of hardware that will measure your display’s colors and tell you how off they might be.

The author bought a piece of color calibrating hardware that was meant to be open in design and work with Linux, as presumably he wants to support these efforts.

But he encountered a bevy of problems, ranging from packages not updated in a while to things that just plain don’t work as documented, and got frustrated.

Understandable, since on macOS or Windows with proprietary hardware, this would have been a 5 minute process. The author is sad and frustrated that the open source alternatives aren’t there.

Also that only GNOME appears to have color management. XFCE and KDE seem to be lacking in that regard.

If you display the same RGB value on different screens (or other outputs like prints) it'll be a different actual color being displayed. Color calibration measures the actual color created and creates correction information that software can use to make the color conform to a standard, so you have better control over the output.

He wrote a pretty detailed blog article explaining his issues and how he got around them, this is all very useful information to someone who is looking to do something similar.

Spending €100 also isn't an insignificant amount, and for that price I would expect what I'm buying to work properly.

...which is just how the whole clusterfuck begins. At the end we know that hardly anything in the whole stack works as expected.

The Linux community will attempt to solve the problem by attempting to create an entirely new color management system, which will get at best 80% done with a handful of outstanding Hard bugs, at least one of which will be bad enough to break the entire thing except on one specific distro/gui/hardware combination.

I could understand you have to calibrate a display if the connection between PC and display would be analog. I don't understand it in the digital age.
