Is there any way to slow down how quickly the color picker moves?
I am finding that when I find a combination I like, when I go to freeze the screen the pickers have already moved on to (and captured) a different combination.
No, it can't be slowed down, but once it freezes, you can tap and drag on the color circles to move them around. You can also edit themes once they're saved by tapping on a theme in your Library and then tapping the Edit button.
I know it's not the answer you were looking/hoping for, but does it help at all?
It does, thank you!
