Why are my Terminal.app colors different from iTerm? I have set the ANSI colors of both terminals to be the same (see 1st screenshot), but the colors for Terminal.app are really bright, and almost unreadable, and not like the colors I set at all.

It's not just the prompt as well. Even with Vim the colors are different. 

EDIT: It's like in Terminal.app, something is overriding colors. B
There has been some discussion on the web about iTerm2's color accuracy being off,

Including a bug report on iTerm2 issue tracker, https://gitlab.com/gnachman/iterm2/issues/3989.

Sounds like it might just be a iTerm2 issue.
