-It is desirable to have a wide mix of themes and colors for the additional wallpapers. Photographs and 
illustrations that would otherwise be too contrasty and with high frequency detail to be a good backdrop are 
perfectly suitable. Starting GNOME 42 each wallpaper shoulc come in two variants, light and dark. While the 
actual difference isn't well defined, the dark variant should try to limit the overall brightness.

-It is recommended to submit wallpapers of 4megapixels and above. Photos should generally come in the 
standard size of 4096x2160px, with no artifacts such as chromatic aberration. The wallpapers get scaled with 
the `background-size: cover` equivalent method but due to portrait aspect for displays being rather rare and 
the texture size being a real constraint we have not switched to square backgrounds yet. Do take various 
possible display aspect ratios into consideration when submitting wallpapers with strong reliance on 
composition. Important elements might get cropped.
