Description Piotr Mierzwinski 2021-06-14 16:26:48 UTC
Created attachment 139313 [details] tabs, dark color SUMMARY As in subject. For details please look at attached screen shots. Using Application style Breeze and color "Dark Breeze" I observe barely visible contrast between active and not active tabs. Notice please that using color: "Breeze High Contrast" doesn't help. Actually this nothing changes. BTW. Checking views in System Settings (i.e. for Plasma Styles) with this color as current we experience even less contrast for highlight. STEPS TO REPRODUCE 1. start konsole or dolphin and open couple tabs 2. look at the contrast between active and not active tab 3. OBSERVED RESULT contrast between active and not active tab is barely visible EXPECTED RESULT contrast between active and not active tab should be more visible, at least like it happens in bright style SOFTWARE/OS VERSIONS Linux/KDE Plasma: YES (available in About System) KDE Plasma Version: 5.22.0 KDE Frameworks Version: 5.83 Qt Version: 5.15.2 (+kde patches) ADDITIONAL INFORMATION

The blue line is intended to be a contrast enhancer. I gather that's not good enough for you?

(In reply to Nate Graham from comment #2) > The blue line is intended to be a contrast enhancer. I gather that's not > good enough for you? Yes. I think is not enough. In my opinion comparing to bright mode this is very poor contrast. And blue line barely marks the contrast in tabs. I think bright mode seems to be more polished in this case. When I run my eyes over the cards is easier for me to find active card when it contrasts enough, even if font in title contrasts then is easier to find such tab. In dark mode in Breeze this doesn't happen. We have only workaround like mentioned line. And because of this sometime ago I started to use dark kvantum style, where I have brigher font for active tab and darker for not active tab. Please check attached screenshot. I think this makes better contrast than line drowing on top or bottom of tab. Notice please that line might be unnoticed under certain circumstances, for example when something in similar color will be placed in very close this line. In my humble opinion this doens't happen if we have better contrast of background like in bright mode or if title is drawn brighter for active or darker for not active tab, if contrast of background for both types of them is worse, like current situation.

I saw screenshots and think that also colour of found could be darker a bit, not with the same colour like active tab. This would be improved more the contrast.

I saw screenshots and think that also colour of _font_ in not active tab could be darker a bit, and not with the same colour like in active tab. This would be improved more the contrast.

Git commit 9d361c9e26747b44f104efe9d545f3877ed6100a by Janet Blackquill. Committed on 23/02/2022 at 18:41. Pushed by ngraham into branch 'master'. kstyle: fix low contrast tabs on dark This fixes the contrast of tabs on dark themes by using a darkening factor on the Window colour, adjusted for whether it's light or dark, instead of using the Shadow colour for both light and dark themes.
