If you want to go for the same color throughout, you can, but at the very least, go for a different finish on the walls vs the trim. Definitely go for a more matte finish on the walls and something more in the semi-gloss range on the trim. If you love the color, go for it!

Wow! First off I want to thank everyone who has taken the time to give me advice, I am so grateful. It might take me a bit to absorb it all, but I have come away with a better idea of what direction to go in for sure. I have decided to forgo to darker greens, as I agree that we can do better. It didn’t occur to me to mention (in hindsight I realize I should have) is that I live in the urban core of Tampa, right between two historical districts. While I don’t have to follow the architectural review boards rules, many of the homes in my neighborhood do. Most older homes on my street are painted very subdued, deeper colors. We just so happened to test a sample of Blue Echo today, so I was happy to see it recommended here by Beth H.: We both really liked it but I didn’t take any photos as it was getting dark by the time I finished up. I have a lot to think about and need to narrow down more samples to try. Again, a huge thank you to everyone who has given advice, now I need to go and try some more colors!

This the BM paint closest to sea salt but gives a similar virtual visual I like a white better, this is BM pure white has a bit of grey

You have to decide what type of MCM you want to follow. Florida and Southern California MCM will be influenced by Caribbean and desert colors. Other parts of the country are influenced by more earthen tones. If it were me, I'd go in the Florida direction because that is where this house is located. I'm a believer climate driven colors. In Florida, they are reflective colors rather than colors that absorb heat. Below is a Palm Springs home. Note the desert influence. Personally, I like the second and third Florida pictures. Grey roof and trim with a softer white body. You don't have any rock trim to drive a decision. You do have the opportunity to go wild with that front door. I'd match a pink flaming paint for the front door.
