The green trim will mean having to often repeat the color in your decor choices, so trim relates and feels coordinated. If that’s your plan, it could be really nice. If not, the trim could be glaring.

I voted white, as I think it will be softer, less broken up and decorating/accessorizing may be easier.

If you want to do something different, painting the ceiling a very soft green won’t feel as patchy as trim might

Pictures always show focal point which is a part of the whole room. When we think about the whole room imagine all the other colorful toys, furniture and upholstery you’ll be adding to the room. So using white trims allows you to add different colors or change the style easily in the future.

they did something similar w/this wall and only painted the trim around the accent. (which is also the perfect green shade for your wall)

In this one they painted everything in the room the same color

Following up on this. We ended up going with green and couldn't be happier! Thank you for the help.
