The differences in the way colors are perceived, combined with natural limitations of electronic devices and the imprecise replacement of colors outside the gamut, mean the colors on your monitor will never exactly match the colors you see with your eye. Cultural conditions influence what our brain recognizes as "pure white." For example, Asians prefer red shades of white, and Central Europeans prefer blue. What the brain perceives as "white" is defined by a whole series of factors, not just the perceived wavelengths. For mixed colors such as yellow – composed of green and red on the monitor – the printer may sometimes be better than the monitor assuming that this color is available as a process color. The eye is particularly sensitive to tones in the green range and can detect far more nuances of green in nature than a monitor shows. Colors outside the gamut appear in replacement colors, which leads to distortions.ĭifferent colors have different effects on the human eye. Image-processing experts use the term gamut to describe the possible colors a device can produce by internal mixing. Another problem is that color values often shift as the image makes its way through the chain of devices, from the camera, to the monitor, and finally the printer.Įach device can only absorb and process colors to a limited extent. The human eye adapts much better than a camera to different lighting conditions and automatically supplements missing information. Colors are lost on the way from the camera to the image. It builds, appears on settings as something functional but offers no functionalities.Anyone who has ever tried to reconcile an electronic image with nature will be familiar with the problem: The colors in the image almost always differ from what you see with your eyes. So, it feels the module is in a zombie mode just a GUI without any possibility to use it. (ICC profile created with Displa圜al, ex DispCalGUI, a software who propose to copy the ICC after creation to colord). It also doesn't launch anything at new start-up. Load/Assign an existing ICC profile to a monitor wasn't working either: The ICC are listed correctly as child of the monitor in the GUI tree, the checkbox can be switched active/inactive to a target profile but switching and applying it has no consequences on the appearance on the color of the monitor. Calibrate a monitor and create a new ICC doesn't work: it launches the wizard (a dialog similar to Gnome2/MATE/Cinnamon) and after replying to the questions/options and pressing 'next' a couple of time to reach the final button, it finally failed and wasn't able to identify the monitor. What doesn't work more precisely is the core of the module: On the bright side, the module still appears on the Settings manager and all the GUI buttons still appears and are clickable. I ran various test on Ubuntu based KDE desktop (KDE Neon and Kubuntu 20.04LTS, full install) to get an idea of the state of Plasma for artist/graphist and it looks like color-management is broken.
