[SOLVED] Black Color in Some Apps. Need to Change to A Light Color

After I installed I noticed the general theme where everything was black.
I changed themes and settings to light colors.
It seems fine (almost) but I sill have:
- Firefox new tab or even google search black background.
- Zim notes has black background (hard to read/ prefer white background)
- The forum here as well (but this maybe the actual background of the forum because other websites seem ok)
- Same for start menu
My theme is Light Theme and Breeze (where its photo shows light start menu not black)

For me it is hard to see links, check boxes or some buttons... etc.

Any way to change the black background (whether as a system setting or as app specific settings)?

Thank you.

as for this forum, you can change the theme (go to https://forum.artixlinux.org/index.php?action=profile;area=theme & click the ‘change theme’ button at the top of the page content)
Wow. Thank you @tiosgz
to me it looks much better now.

You can disable the dark theme on wiki by blocking theme css files with your blocker (I described urls here):
https://forum.artixlinux.org/index.php/topic,3168.msg20606.html#msg20606

System color scheme, you did not mention your DE so I will assume it is mess.
You have to setup proper clor scheme / theme for gtk2, gtk3, Qt.
Qt has 2 options (at least in KDE/Plasma) there is Theme settings and also Colors settings and both need to be adjusted. Nous even made simple video example how to do this.

I rechecked themes as you mentioned. Everything is OK now.
Still Zim has a black background/paper. I'm on KDE.
Maybe something related to Zim configuration in particular.

UPDATE: in Themes -> Application Style -> I chnaged GTK theme. This did the trick.
You gave me the clue where to look.
Wonderful support as usual.
Thank you.

This wiki article explains how we implemented dark theme in Artix.

There are some tips on how to use another theme, if the DE doesn't obey the user's commands.

Hello limotux,

For my Artix Linux XFCE OpenRC from the artix-xfce-openrc-20210426-x86_64.iso using Calamares.

I don't use Thunar, but Dolphin.

When choosing the Adwaita theme, I notice that the visual themes are mixed.
The background of Dolphin, Gimp, or some configuration windows is black...

I found an absolutely unscientific method to fix it (but it has been working for over a year):

Reinstall all the packages present.
Code: [Select]
sudo pacman -S $(pacman -Qnq)

After this "cure", all the colors are correct everywhere ... on condition of commenting (add # at the beginning of the line) in / etc / environment the two lines:
# QT_QPA_PLATFORMTHEME=gtk2
# QT_STYLE_OVERRIDE=gtk

Code: [Select]
sudo nano /etc/environment

P.S.
Personally, I change the background color of Dolphin:
edit ~/.config/kdeglobals and modify
[Colors:View]
BackgroundNormal=220,220,220

@tintin Out of curiosity, don't you get the same effect by just commenting out those variables in /etc/environment?

Hello,
No, it doesn't work by commenting out these two lines without reinstalling all the packages.

Systematically after a new installation of Artix openrc XFCE, I have this phenomenon (wrong colors when I choose the clear Adwaita theme).

Alright, I could install an Artix-base to see, but I'm a bit lazy. :-[

So, I don't ask myself any more questions, I follow this Windows-style procedure and the housework is done.  8)

There must probably be a problem with dependencies, a nonexistent configuration file or a missing link that I couldn't pinpoint ...
