Yellow? Different green?

I was also thinking of yellow - or perhaps orange.

I like green too, but in this application I don’t think there’s enough contrast between the door and the siding. Maybe a paler green would have been better. I don’t care for the two-tone green look either.

The blue siding and crisp white trim look great.

I would paint the door orange, rather than any shade of green. Orange would look great with your siding color.

We have blue siding and painted our door yellow. SW Butternut to be exact. It looks great. We also have barn lights over our garage in the same color. Looks sharp.
