Q: Dark Mode for the finder/safari/mail/etc

I just upgraded to Yosemite and I am very pleased to see the addition of dark mode for the menu and dock.  This such a basic feature that I've needed since I started using macs ten years ago.

I often use my macbook and ios devices in low light environments for work.  Venues, theaters, bars, etc.  Even on the lowest brightness the screen is distracting to others and compromises my night vision, not to mention causes additional eye strain.  More and more these days, IOS and OS X devices are used by artists on stage and by sound and lighting engineers off stage.  It's a major bummer when you open your finder and and a blinding white light hits you.

For dark mode to be useful it needs to address more than just the dock and menu bar.  Ideally, it would invert colors entirely EXCEPT for images, videos, flash, etc.  I would settle for this only being available in the finder and safari.  I'm aware that I can invert all colors already, but its annoying that I have to view pictures and everything else in negative as well.

It's a bit frustrating that this was an option in the last version of windows I used ten years ago but has been impossible in OS X.  I have every confidence that Apple can make this possible, and I'd really appreciate it.

Thanks,
