I can't really see the colors. Neither of those colors look like they will pop. Plus, the storm door will obscure the color. I would plan to paint the storm door, also. Classic color would be navy or black for brick houses. SW Naval, BM Hale Navy,

I don’t disagree with @jck910 but the classic colors of navy or black are too dark. As you noted already, the darker colors all looked black in the all day shade - not color popping. I agree the storm door should be painted too. Of your 2 current choices, mine is Newberry Green. I’m looking at shrub to right of door - that IMO gives a pretty good idea of what the NG color will look like against the brick. Enough pop? I’d keep looking to be sure. I would want the color to be darker than the siding as the NG is. Whatever color you land on, please plan to change out the 2 large plant pots to coordinate with the door color. I’d also move the small pot away from the blue one & add it to the other side in the corner. It’s the odd # thing of design & also the 2 pots to right of door looks crowded. I know you didn’t ask about that but hey - every question gets lots of unsolicited advice! 😉
