I have a custom color for my wallpaper. After updating to Mac OS 15.4 any custom wallpaper color shows as white. I can choose a photo. I can choose a custom color. Those work. But if I choose a custom color, white. How does such an obvious bug make it through your quality assurance and beta without being fixed?

Good question. I just ran across that myself.
I always use a gray background that matches the gray of my GraphicLite color viewing booth. When the 15.4 update was done, it came back to a stark white screen.
Playing around in settings, I got the same results you did. Pictures, fine. Any of the 19 default colors, fine. Any custom color, white, no matter what you choose.
Verified it was the OS by creating a new account and the same thing happened there.

No one here even knows if Apple is aware of it. Feel free to send Apple feedback.
I have now sent feedback to Apple.
I am seeing the same issue after installing 15.4.
"How does such an obvious bug make it through your quality assurance and beta without being fixed?"
Indeed. As indicated in this thread, temp. work-around is to create a small image in the solid color that you were using previously, and then use System Settings => Wallpaper => Add Photo to set.
Got around it by cheating a bit. My custom color was just a gray tint with RGB values of 153, 153, 153. So I created a 10x10 pixel, 16 bit PNG image and put it in my user account Pictures folder. Chose that as my wallpaper and it's back to "normal".
I eventually made a 4k image (to match my monitor) and filled it with something resembling the color I used to have for my wallpaper. Unfortunately I did not do a screen shot to save that color. But it will do for now.
You don't need that big of a file for a simple, flat tint. It unnecessarily takes up more system resources.
Crop it way down to a tiny image. The OS will automatically tile it to fill the screen and it won't look any differnent.
I just tried showing all colors and there is my mid gray I use to use.
Same here MacBook Air M2. Annoying as I don't like any of the standard colours. Does anyone know if Apple are working on a fix?
I had dark grey before upgrading. Now it is white. Another problem: My Mac is in my work's InTune, so I can't change it to nothing else, since the upgrade changed it to white.
I made a JPG with my prefered color... and... choose image.... YESSSSSS.... very good idea... and it works ..... THX
