I suggest you cross post this on the Home Decorating forum.

I am not familiar with those shades of blue. When I was selecting exterior colors, I was amazed by how much lighter the colors look when tested as compared to looking at chips. There is no getting around buying samples and doing color boards.

And there is even a difference in how the paint looks depending on what side of the house it is on. I used Vermont Slate on my east and west facing porch floors. The west side looks much brighter - almost too bright - even in the shade with the sun on the other side of the house.
