Color looks spot on to my eyes, congrats on the new camera.Nipped out today between the rain and grabbed a few shots on the new camera,what do you think about the colour is it too strong.
Saturation looks good to me (and pumping up the saturation, vibrance, etc. is a REAL pet peeve of mine).
I notice you're using a +1 Sharpness setting in-camera. I might suggest you try bumping that to +7 and see what you think. That was the "sweet spot" for me and made a huge difference in the image quality I got out of my 5100.
