it's not the best rendition but this might give you an idea if you are on the right track or not.

this is SW In The Navy

Thanks that looks sharp but I fear it will fade quickly

Are the shingles painted or stained? How about white?

Sage body would be good.

Or a little bit darker

White/off-white/ivory would look so beachy

I'd go for a pretty sea glass look. Read the details for these to get paint names.

I don’t care for the SW Shertaton sage either but the lighter green one in the picture below ( by celerygirl) is what I was leaning towards with white and navy blue trim for contrast

If you do the lighter sage, how about a blue on the lap siding in the gables?

Navy Blue trim? no

I didn’t mean trim I meant white trim with navy accent around windows
