I was able to go to People and options in past and change colour for contacts & message bubbles. Since latest update that color feature no longer shows up. What happened and why?
Welcome to Android Central! Are you using the Android Messages app? If so, that option was taken away in the latest update. It's causing a bit of an outcry: https://www.droid-life.com/2018/09/...the-new-android-messages-even-with-dark-mode/. If it's important to you, send Google feedback through the Help & Feedback option in the Android Messages app.
