Created attachment 176059 [details]
A comparison of 4 instances of bottles. On the right side are two instances running in X11 and on the left side are two instances running in wayland displaying incorrect colors.

SUMMARY
When running a GTK4/libadwaita application on the plasma wayland session, the colors drawn are slightly off from what is defined by libadwaita. When running on the plasma x11 session or using GDK_BACKEND=x11, the colors are drawn correctly.

SOFTWARE/OS VERSIONS
KDE Plasma Version: 6.2.3
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0

ADDITIONAL INFORMATION
With default libadwaita colors, the difference isn't super noticeable to the naked eye, so in the attachment I included an example using a custom theme that makes it more obvious.
