Have you ever chosen exterior paint colours?

I feel like it's a major decision compared to inside!

Our builder and others in the area paint the garage door(s) different than the front door(s) (annoys me, I want matching!) and we have another spot that might need painted too. Our house is just a year old, but the paint the builder used (chipping already), plus the different colours of each doors, I want to paint!!

I know I want a brown, but I feel like this isn't something I can solve for myself on Pinterest, lol. Is it just trial and error at my own expense, or is there something out there that can help me ensure I choose something that will look sharp with our brick?

Realize this isn't a problem, but it's definitely something I've never done before.
