Your home is beautiful! I would do a mid-tone gray with white trim. Something that accentuates the strong simple mid-century lines, and also complements the beautiful landscaping. A darker blue color could also be lovely.

I love the blue.

For a similar look consider Benjamin Moore 'Wales Gray'. They describe it as a traditional blue with gray undertones.

As for the roof, not too dark a charcoal, and a uniform shingle color.

Here is the darker version called 'Silver Mink' It won't wash out in the sun.

I love your home. Not sure why you think adding siding on top of concrete block/stucco is money worth spending. Maybe a skim coat over the block to smooth it?? Here's a ranch house with siding, and I'm not sure you should downgrade your home with siding.

I like this color on stucco below. It could look great on your home.

A metal roof as suggested ^^... with Silver Mink:

SW Interesting Aqua, Alabaster and Mandarin ...

suggested above ^^

A corrugated metal roof might be a very good choice for your home.

Check out these colors:

• Granite Peak SW 6250
• Laurel Woods SW 7749
• Autumnal SW 6361 (for a door, possibly?)

I would go with gray/charcoal/black roof , off-white/white siding and gray window trim.

White on white or off-white looks good as well

If you just paint the stucco, you can use the money for a metal roof. The soft blue shades posted would be stunning.

I would reconsider the siding idea. Several of the above photos are more interesting renditions of your home.

Thank you to everyone for taking the time to comment! To clarify, we do not have stucco, we have 1940's cinderblock that is in pretty bad/uneven shape. The painted cinderblock is not a good look, nor is the cheap t1-11 siding on the back addition. Stucco homes in our area tend to crack or have moisture issues due to humidity. We want one siding type to bring the whole house together. Ongoing maintenance is a factor, as well.

The v-groove siding we selected will have mitered corners (no corner trim boards) for a modern look. It is not the Hardie plank "lap" siding put on most traditional homes. We are also considering adding stained wood to the "bump out" in front with the 3 windows. We could do that horizontally or vertically, though I am concerned about this looking too "on trend" now and dated in a few years. Currently that bump out is vertical painted wood paneling that has a lot of rot.

We are replacing the roof, if that was unclear. We'll need to stick to shingles due to cost as we also have to replace a large flat roof with costly TPO.

Additional recommendations welcome! Thanks again!

" Hardie V-Groove horizontal siding "

What siding is this as I am not sure that I have seen a V-groove horizontal siding?

I would skim coat as mentioned for the cinderblock. It sounds a lot better than more siding and would give a great look.

If the vertical paneling on the bump out is original, that could be a consideration to restore the look.
