iTerm2 v3 Solarized color sets have ANSI bright colors as greyish
iTerm version 3.0.0
I've not noticed this before and suspect that the appearance settings changed in the version 3 upgrade...
The two Solarized color sets show the ANSI bright colors as shades of greyish, as shown in the iterm_solarized_default.png
screen cap.
I would expect them to have colors in - as per the hacked together iterm_solarized_tweaked.png
screencap (this color set was a quick hack and could be much improved).
