Ventura 13.0.1 caused colors to render screen images and text illegible.
How do I correct this? My MacBook Air M1 is essentially inoperable.

Hey there Macrok,
We'd like to confirm, do you notice any issues with the screen after you restart it or press the power button until it shuts off? If it persists, let's check to see if you can boot it in safe mode since this can help rule out possible startup software issues. Use these steps:
Apple silicon
1. Shut down your Mac.
2. Turn on your Mac and continue to press and hold the power button until you see the startup options window.
3. Select your startup disk, then press and hold the Shift key while clicking “Continue in Safe Mode.”
4. Log in to your Mac. You might be asked to log in again.
Intel processor
1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.
2. Release the key when you see the login window, then log in to your Mac.
3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window.
