I believe it makes sense for the slider to represent the strength of the effect, as 0% represents no change and 100% represents '(fully) on'. Removing the numbers to clarify that the sliders do not directly represent colour temperature would likely be objectionable as users might want to set specific values (perhaps for consistency with other systems). This could be improved with a custom slider that does represent colour temperature, visually. This is unfortunately not practicable, so I will mark this as RESOLVED INTENTIONAL. It does, but only if you remove the numbers. For comparison's sake, let's look at what other systems and applications do: - GNOME has a slider that goes from cool to warm, but it presents this graphically and omits numbers - Cinnamon has a similar approach: graphical representation from cool to warm - Windows 10 has a slider from warm to cool, with a graphical representation of this, but with no numbers - Windows 11 provides a clearly labelled "strength" slider with no numbers - macOS calls the feature "night shift" and provides the third example of a slider where strength increases going to the right, without any numbers - Android only shows an intensity slider like Windows 11 It looks like all other platforms do not use numbers and order from cool to warm (save for now-EOL Windows 10). All applications where colour temperature numbers are used, however, use the number ordering as intended: - All Redshift GUI implementations I found use numbers and correctly order them - f.lux provides numbers and correctly orders them - LightBulb (Windows) provides numbers and correctly orders them - SunsetScreen (Windows) provides numbers and correctly orders them - Twilight (Android) provides an unlabelled intensity slider - Red Moon (Android) provides numbers and correctly orders them - broadening the view, GIMP provides a colour temperature adjustment feature with correct LTR ordering It looks like there are no consistency concerns with other systems, given how every single other OS and DE does not provide numbers. All applications which provide numbers, however, also correctly order them. I have not been able to find an example of a night light feature which operates like Plasma currently does. If consistency is a concern, then I suggest changing the current behaviour as it is inconsistent with every single other system and application, irrespective of what they do. macOS is obviously the fourth example. I added Cinnamon before it and forgot to update the text; sorry about that! |
