15.4 Wallpaper bug?

chown33 said:
It's pretty easy to do with Apple's builtin Preview app.

Open any image file, and choose to Annotate it.
Pick the Rectangle shape.
Change its Fill Color to the color you want.
Draw a Rectangle.
Screenshot only the filled Rectangle.
Use the screenshot as wallpaper.

Annotate an image in Preview on Mac

In Preview on your Mac, sketch and draw, adjust colors, and use notes, text, shapes, and other tools to mark up an image.

Oh great tip, thanks!!!!
 
The image-file trick doesn't help me--I have three monitors and to make them look similar I had to create custom colors for the monitors on each side of the LG UltraFine. So now it's distracting when I move a window to a different monitor and the white point is all different. I've been testing dozens of color profiles in Settings/Displays and I'm pretty grumpy about it.
 
Another thing to try would be the above image fill/screenshot but, save it to Photos. Then use that color in Photos to set your desktop image. Photos has always been better for me to set desktop pictures.
 
Just created an account to post this. You can set you background color and then create a transparent png file. Once you select a color just switch your background to the transparent png. Whatever you selected as your background color will stick. Not sure if it will work with different colored background. I attached a little transparent png. Just select the image and "Center".

I have an M1 Macbook Air and I just "upgraded" to Sequoia 15.4 and my background is a blinding white. I can't change it. Does a human actually test these "updates" on actual machines or do the the developers just do unit testing?
 
Just tried this and it worked fine. I'm running Mac OS 15.4.

1. Make a new document in Pages
2. Insert a rectagon shape and fill it with the color you want
3. Press Command Shift 4 and select as much area of the shape as you can to make a selective screenshot
4. Click Done and save to Photos
5. Open Photos and select your photo of your new color
6. Click the Share button and select Set WallPaper

what a ridiculous bug

Indeed. Just updated to 15.4 and immediately see the white wallpaper. I have now come to believe that Apple engineers have become grossly incompetent. Especially when I hear that this bug was discovered during beta and NOT fixed for the release.

I can’t set a custom wallpaper color on Sequoia 15.4. The background changes to white after selecting a custom color.

I can only select from one of the preset colors.

Is anyone else having this issue?

Yes. I find the default white too bright. I'd like a plain mid-grey (50% black) and cannot set it.
 
As of Sequoia 15.4.1, Wallpaper has been fixed, i.e. the + button does produce a choice of plain background colours. I now have a 50% grey background. It may have been fixed earlier, but I had not noticed.
 
Sequoia 15.5 broke mine again and the fix I did no longer works. I always get the black screen rather than the white.
