Oh! Cute house! Since it's a little dark under the porch, I would definitely choose a light or bright color so its very visible. I tihnk the aquamarine I posted would look very nice. What colors do you like?
Here's some fun house number ideas:
Mounted the numbers in turf.
I love these more modern number signs. The wood is nice or you could paint the background to match your door.
Or you could paint the numbers to match the door!
Any of these could be done vertically too, depending on where you plan to mount them.
