Darren, that made a big difference! You can visualize the scenery. On the sky blue, paint a test area and go away for a while. Then come back and get a first impression. getting the shade that you like will be a pain.
I went with Tibetan Sky from Sherwin Williams in egg shell. I looked at the sky on a perfectly clear sunny day and chose what I thought was the color just above the trees on the horizon. It's very light, but it reacts to lighting changes. Oh, I also put their commercial white primer product on first to get exactly the shade that I wanted. The undercoat definitely impacts the color of the finish coat.
