Do you have a closeup of the brick? Is the mortar grey? If so, aim for a color that matches the mortar.

what color is the mortar? if you are able to match/not fight with that, it will look great.

kathryn and i think alike....

There's the brick - mortar is definitely a light grey. My wife really likes knitting needles by Sherwin Williams. Thank you all for your thoughts!

match the mortar and choose a color from that strip, and you'll have a stellar result.

Nice home and lot.

With your roof color, if you keep the shutters, keep them black.

I, too, like the "knitting needles" color

however with your brick, that may be a bit light.

Pewter Cast, two shades lighter,

is worth considering.

If you're considering doing more than painting, consider removing part -- but only part -- of the brick, replacing that half wall of brick the exterior wall of the single story part of your home that is underneath the porch with vertical siding the same color as you choose to paint the rest of your siding.

If you removed that part of the brick, you could reuse it to create a raised flower bed or outline a sidewalk leading to your front porch.

You could also go bold with the front door(s) -- perhaps a deep burgundy with whatever gray you ultimately choose for siding.

Beautiful tree in your front yard. I'm aware that very little grows well in the shade of large trees, especially if some of their roots are above ground but … stones? rendering that much space inaccessible? Have you considered a front yard patio around that tree using the stones and/or mulch only where you cannot place pavers or mow?

What you don't want to do is place dirt against the trunk
