I have just updated to iOS 12, seems innocuous all in all, but I have just noticed that when sending a SMS the balloon colour has changed from a light vibrant green to a hideous dull, dark green. This did not need changing and is greatly for the worse, do you think that Apple is trying to tell us to think that people who use other systems than their own are dull boring and depressing ? I wonder if this can be altered. I have just noticed that the head bar on the iMore app has changed to the colour of rotten mustard ! Also, is it possible to de-clutter the increasingly irritating tool bar at the bottom of the Messages screen ?
