I happen to find this website( a few months ago. It’s a great and simple color schemes generator that I have found on the web. Plus you can book mark your color scheme to go back to anytime. Be sure to check out the tutorial too.

Detect Display

I work on multiple displays and have one monitor that I have to manually adjust the resolution. Before upgrading I was able to use “detect display” under system preferences > display and it would automatically adjust its resolution to something more bearable than 800 X 600.

I noticed after upgrading to Mavericks if I went to system preferences > display I noticed the “Detect Display” under the color tab was missing. On a happy accident I discovered that if you press the Option button on your keyboard while in the color tabs the “gather windows”button will change to “Detect Display”.
