Nice Mark! I’m looking for an app!

if you just want to try colors, SW colorsnap.

Brick and Batten does complete renditions for you, for a fee. You might even find a similar house to yours that they've already done.

any of the other apps that will let you do realistic looking modifications are all going to cost you money.

lets see your home

Thank you Beth! I’ll look into those! This is the house with a few modifications including adding a downstairs. I’m looking at green siding and white-ish color brick around the bottom. It’s so hard to pick white, or off white trim, or tan trim or white vs black windows. (Which we are sticking with white). So many great options out there it’s hard to decide.

If this is the model home, can you post what the options are for the outside? I’m assuming the “all rock” exterior is not what you want. Green siding comes in a ton of different shades.

Post the trim options too.

Here is so rough visual for green siding and white trim.

I think green would work good with wood and existing stones.

you need to get an actual sample of the stone so you can see the undertone it has. then pick your siding color. ditto w/a color sample of the roof.

This was a house plan we found online and are basically customizing it to us.
I plan for a lighter brick to go all around the bottom half from under windows. Black windows. Green siding. Cedar details. Green trim, except cedar above the windows. It’s just so hard to picture this and I go back and forth on all the colors. Color schemes are hard! Thank you so much for all the suggestions. I love the input.

Ok, well if you're able to pick your materials, then start yourself a 'mood' board. order samples from each company so you'll have them on hand. (stone, brick, roof samples, etc) even the cedar. Get some small cedar pieces/boards w/the stain or the varnish you plan on using. (Cedar will naturally gray if you do NOT apply a UV varnish to it)

once your have the ones you like, THEN you pick your house color. it's easier to match paint to brick and stone than vice versa.

I see what you're after.

Take a look at these SW dark green colors they did on board and batten

SW Cascades:

This is Agean Olive Black w/the wood and lighter stone accents. Black windows.

you could even do a creamier or white wash brick. here's one w/a lighter sage siding and gray/gree shutters

Lighter sage colors

If you want a light stone w/warmer tones to it (to play w/the cedar) try something like this one

Any of these colors would get you that look

another lighter stone w/bits of the warm tones

If you want to stay w/the green tones, for the white trim, use a white that leans toward the green end of the color wheel so it works w/your green siding.

If you like cooler greens/gray with a grayish/silver tone stone:

for example, this Alaska white quartzite ledger panel accents would work w/these cooler tones.

This color palette below would be perfect for that Alaska White

Or, even this one. you see how the green tones lean a little cooler?

The White Limestone in this format is also really nice

as an example, that stone, or similar stone, might look nice w/this color green, white windows and a lighter, tan roof. the darker cedar plays well w/all of it.

There are so many variations of stone combined w/roof and windows, that choosing a green color should actually come last.

So, get yourself your samples and start building from that.

THANK YOU!!! I appreciate the guidance so much!
