Pixel 2XL SMS texts in Messenger App changed to pastel

[Azpixel]

My SMS messages app has started displaying messages in pastel colors instead of in bold primary colors. I also can no longer change the color assigned to a contact. I updatesd to Pie a couple of weeks ago and it was fine... It just changed today out of nowhere. Any ideas on how to change it back?

Did the app possibly update? The Phone and Contacts apps have updated and now use those colors.
