I'm not a designer, but I like the blue!

I'm liking that blue on your sample pic. Just the right shade and brightness for the style of the house, and will play off the siding very nicely.

I like the lighter color shown in the middle. I think it will work soooo well with all the other colors shown, including the white trim.

I'd recommend a darker tone of the color on the far right. Remember when you paint that little swatch it is deceiving. The paint on a home's exterior when put on the entire side appears much lighter than the little
swatch. Keep it more neutral, the blue is too funky for an exterior. Good luck!

P.S. I'd also paint the trim ivory, a warmer tone and not the bright white ( it looks cold as it has blue undertones).
