Solution for: #79: DigitalColor Meter RGB color space defaults on Snow Leopard

This solution might be pretty dumb, but it works partially. The DigitalColor Meter.app stores its preferences in /Users/<yourname>/Library/Preferences/com.apple.DigitalColorMeter.plist. Open it up and look for the property value dcmColorSpace, which sets the default color space choice at launch time. It is set to 1 for me. If you set it to 4, that corresponds to the fourth choice in the menu, which is "RGB as Hex Value, 8-bit".

So while it doesn't completely solve the problem, you can set the default to a more reasonable choice. As I do CSS work a lot, I set dcmColorSpace to 4 to get the RGB in 8-bit hex.
