Since I upgraded to OS Monterey the login screen after I start my laptop shows the purple shades that are literally called "Monterey"
I really don't like the colors! Looking through system preferences I don't see a way to change the image.
Icon yes, but not the screen? Is there something I'm missing? How can I change the image?
I *really* don't like the colors!
MacBook Pro 13″, macOS 12.0
The pre-login boot wallpaper now loads from a sealed snapshot. It is not editable.
macOS today operates by separating the system files and the data files into two totally separate volumes. The system files are "sealed". It is, essentially, a read-only volume which Apple distributes. Since the hard disk is encrypted before you login, the computer does not have access to anything other than a little metadata associated with the accounts (username and a small icon and that's about it). Once you enter a password, the data volume can be decrypted. The computer then essentially "merges" the system files and data files together in real time like a zipper through a series of firmlinks.
macOS now boots in a state that is always fresh and identical. Only once you login do all the changes you've made (including wallpaper) become visible to the system.
Under Big Sur I changed my desktop wallpaper to one of my own pictures and it also showed as the wallpaper on login. After upgrading to Monterey it is still the same. So all I can suggest is to set your wallpaper to one of your own pictures and see if it appears on the login screen.
It's very possible to modify the startup image in Monterey and I was able to do it.
First follow the instructions given by angelica241 except that there's one last step that you have to do.
1) System Preferences > Users & Groups.
2) Open lock to make changes.
3) Right click on user in left column > Advanced Options.
4) Copy UUID value.
5) Go to /Library/Caches/Desktop Pictures.
6) If it doesn't exist create Desktop Pictures folder.
7) Inside Desktop Pictures create folder with UUID value as name.
If it exists, just open folder and put the picture you want in it and name it as "lockscreen.png". It has to be a .png picture.
8) Then close folder and right-click on folder > Get Info.
9) Open lock to make changes.
10) Grant permission to Read & Write to user, admin, everyone.
11) Close lock
12) Open System Preferences >FileVault and disable it.
(The new startup screen will work.
13) Restart computer
14) If you enable the File Vault again, the startup screen won’t work anymore.
yes that works. but it's a rather involved solution. and if you are using a single user and file vault turned off, as needed for that solution, there's a much easier way. please see https://discussions.apple.com/thread/253382773

Have you tried Apple menu > System Settings >Users and Groups > Login Options > (unlock at the bottom) > set Automatic Login to Current User (admin) - guest user has to be off
This worked for me on my new MacBook Pro
Have you tried this?
I’ve just found out the reason why I get a personal login wallpaper, it’s because I’m a single user with guest user login turned off. With guest user turned on it does show the default purple wallpaper.
• I am running macOS Monterey.
• I turned off the 'Guest User' Account under - System Preferences/Users & Groups - (This is important - I believe that you can only have one user account active for your custom Lock Screen image to show up)
• I searched for this folder - /Library/Caches/Desktop Pictures
• Your UUID folder (crazy long name of letter and numbers) is in the above folder you searched for.
• Find this file 'lockscreen.png', and replace it with your image and the same name - 'lockscreen.png'
• Restart your Mac
This tip works for me for the multiple users I have on my Mac. It allows the individual users to have their own logon screens. (I previously used it for Big Sur, but went back to Catalina, where it continued to work for my recent upgrade to Monterey.). However, it does not solve the initial logon screen which shows all users to start initial logon. Just like Big Sur, Apple blocked any user customization of this screen, which continues in Monterey, and again as noted in comments by users, ignores the repeated calls for a return to user customization options without any comment or response from Apple about why the change or if any return to sanity will ever occur.
This is where I'm at as well. Using my 2018 Intel MBP, I was able to customize the login background for each individual user, however, the initial startup screen (from which you would select the user logging in) remains unchanged:
This worked for me: I already had Guest User turned off, so went into Desktop & Screen Saver pane and first set the Dynamic Desktop (I actually like the changing Monterey Cliffs, although Catalina Island was better). I then selected the Pictures folder and Change picture. Now after a shutdown I get the cliffs and the wallpaper cycles through the photos in my Pictures folder, just like I wanted.

How long do you leave the login screen on? I dislike it also but sign in immediately and it's gone. If your iMac is in a secure location, like your home, you can avoid it entire by bypassing the login screen entirely.
Googling seems to show that it is not possible to change it in Monterey. I followed the instructions for previous macOS versions and they do not work for Monterey.
This only works under following conditions
This guy and this YouTube video explains how it’s done. And clearly Apple should make it easier than this. https://youtu.be/8fFNVlpM-Tw
Worthwile trying this - it worked for me
