Here is something, but it is contemporary with an led light. One of my personal pet peeves is not being able to read the numbers (I'm a Realtor so I see this a lot). These might be too big for you as they are 5" tall, but no one will miss them: Here is something without the LED light and a slightly smaller

I think you can have modern house numbers. Your house coloring is modern. Here is a link to a website I send clients to to buy their house numbers. http://www.architecturalnumbers.com/index_23.php?catID=23&file=index.php Also for planting I feel like leafy plants should go along the foundation and by leafy I mean like hostas. Tho I don't know if those grow in ur area since there is no zone. Maroon would be a good contrast in lead color if you could find shrubs that grow in your area.

I know you asked about numbers...but those steps leading to house don't look so safe. Wider stairs with a railing would be better and look better also. As far as numbers. Top photo on the left side above the bush, to balance out window on the other side. Bottom photo, on the right side for the same reason.

@Patricia Colwell thank you, I know I don’t really like the shutters thought about changing them to black. i feel like if I take them off in my house will look so plain definitely something to think about. Great idea to use paper first so I know what size I like
