For the fireplace inserts go ahead and do the green order a second set of panels that you store that are more neutral. In 10 years or five years you may not like the green anymore. It's possible you won't have access to different colored panels at that time. As for the color I like the ideas of going into those silvers it would coordinate very well with your blue couch and it will pull the blues out of the curtain panels. For the wall coloring use the warm golden color in the drape. There is one piece of the flower that has this color and it will balance the weight of a dark couch. If your room is small don't go too dark in this color. You could use it on the main wall and pick two shades lighter on the other three walls.

I love a QUALITY paint job. Few people know the ins and outs of a quality paint job but, a seasoned painter for INTERIORS will have many techniques and processes to dial up the end result. I love my painter and I listen closely to his advice and he is so expert (40 years) and good that he makes it look effortless. BUT IT'S NOT. Will find and post favorite picture of painted trim here. I think the secret is style and proportion of trim and then the quality of the finishing. Did you know most paint curing really needs 2 to 3 weeks to set up as a really good tough finish? "In a hurry" is the curse we mostly experience for improving interiors. I wonder sometimes how different things would be if people took the right amount of time to do things in the time frame related to that finishing task!

Photos would help us a lot but mint and grey usually goes well with charred oak.

Try a light warm gray
