Can I change the colour of the text bubbles in Messages (Mojave OS)?
I would like to change the background colour of the text bubbles in Messages on my MacBook Air. The colours are really bright, and they cause eye strain in some lights. Also white text on grey background is an accessibility issue for the visually impaired (not all of whom need to switch over to an Accessibility mode - they just want to choose an appropriate colour!)
MacBook Air 13", macOS 10.14
