Maybe these will help if you want blue

You may even look at a burgundy or a dark green. Both would also work in my opinion.

I never like blue with brich but if the siding stays blue I think a darker blue in the same color way for the door .

Any chance you can replace or eliminate the storm door? If it needs to stay, I find that color coordinating that with the entry door looks best. Otherwise the actual door isn’t appreciated as much.

Right now it's hard to see the front door and any detailing on it isn't very visible. If you want it to stand out would suggest a very light color.

I like the first blue Maureen used. It matches your siding beautifully

In terms of color schemes a bright yellow would be eye catching here! https://www.buildersservicecompany.com/how-to-coordinate-exterior-house-colors 

My vote is dark blue too.
