tmux windows inherit the default color scheme/theme instead of the one from the host profile.

Thanks for filing an issue! Please answer the questions below so I can help you.

• iTerm2 version: Build 3.0.4
• OS version: 10.11.6
• Attach com.googlecode.iterm2.plist/com.googlecode.iterm2.plist here (drag-drop from finder into this window)

Detailed steps to reproduce the problem:

1. Set the background color to "red" in the default profile
2. Create a new profile and set the background to "green"
3. Open a tab with the new profile and run: ssh -t remote_machine "tmux -CC new -s test"

What happened: A tmux window opens with a red background

What should have happened: A tmux window opens with a green background (since it was called from a terminal with a green background)

Milestone changed to %Review for next version
