The multicolor stones sounds gorgeous! Although I personally feel like that would be harder to wear every day. My personal choice would be RG with 4 diamonds (I like how they look spaced out)
This hasn't been mentioned yet, so I thought I'd throw it out there. I remember a previous poster saying that the LOVE with diamonds and without have different widths and thicknesses. When she stacked a plain with a diamond, you could tell the size difference, and it was enough to bother her. I would suggest trying on in the store - since they'll all be different colors, I think you should be ok. But just it case it bothers you...
