I saw a green with a white roof in St Petersburg/Clearwater area of where I live yesterday for the first time. I liked it. I thought it looked nice on the C-HR. It was the color I would not personally chose as its not my style for me (but I did like it). I have silver and I do wish I had gotten the white. Even though the silver is nice and it changes tones of silver in different light. I really like the white best. They just did not have it in stock for the premium model when I purchased and I already had a white vehicle as our other car, so silver it was.
First of all, welcome to the forum and congrats on the CH-R. White is always a good choice in color, as its one of the most popular options available. Should help both with resale and keeping the car clean. That green color is pretty rare to come upon, and I think there is only one owner on here who was able to secure one and it involved some searching around.
Can't really tell you which color to go with as it's your car. I did some across one suggestion that seemed to help with paint decisions; what color do will you be happy with 3 years down the road? You'll be looking at the C-HR day in and day out until either your lease is up or you drive it into the ground over the course of years. Which paint will you want to look at every day?
I like green because its not a color you seen often, especially the green offered here.
On the plus side by going for a more simple color it means you have far less to worry about, colors as vibrant as that green often fade over time in the sun
