Image file which illustrates the issue.

SUMMARY

Whenever I set the accent color to be based on the wallpaper, every time I set a black, grey, or white image as wallpaper, the accent color is set to blue instead of a monochrome color. Occurs at least on Wayland.

STEPS TO REPRODUCE
1. Set the accent color based on wallpaper in the system settings.
2. Set a monochrome image (black, grey, white) as wallpaper.

OBSERVED RESULT
Color is set to the default blue palette.

EXPECTED RESULT
Color should have been set to a shade of grey.

Occurs on X11 session as well.

Can reproduce. Looks like in this case it falls back to the color-scheme-provided highlight color.

This *may* be intentional but I'll agree with you that it feels like a bug. Gray accent colors are fully supported so IMO it shouldn't fall back to the color scheme highlight color here.
