I knew you'll say that. I'm leaning now to D600 but I'm still crossing my fingers + toes that 6D sensor will be better or at least perform somewhat close to D600. I love Canon colors. A lot of my friends are using Nikon but somehow they can't produce the colors of Canon. A lot of them got D90 and D7000 but they still envy my pictures. I'd hate to switch but as I said before, I'm at the crossroads. Whatever I choose, I know I'll stick with it for a very long time.
Ah yes... Canon colors. Well, that's easy. Use the vivid setting on any other make of camera and there you are - Canon colors!
Oh and anyway - RAW format lets you fiddle with your colors as much as you like in post.
Nope. You can approximate but color gradations is still different. A lot of Canon professionals will attest to that. Vivid settings for landscape? Portrait settings, very different. For landscape, you may argue that at vivid settings or more saturation/contrast/hue, you'll be able to approximate the colors for Canon and Nikon either way but for skin colors, I don't think so.
honestly, having shot both, post processing has made all of this color issues meaningless and neither system has any meaningful advantage. I'm more concerned about things post processing can't easily overcome. Like single exposure dynamic range which canon trails by a huge margin and the low ISO shadow banding noise that plagues canon sensors.
