Maybe a soft sage green?

I was thinking a soft green too.....it would probably compliment the wood trim nicely.

That it would.

I would stay away from the orange.....reminds me of hunting vests. Love the sage green suggestions.

reclaimed wood is very current right now, and the deer heads would love it.

I, too, was going to suggest a sage green. The Orange would be too close in color to the trim. Sherwin-Williams Softened Green looks good to me (photo 1). S-W Lemongrass is another possibility, with a limey look to it (photo 2)

honey brown/beige. Toss on some pillows and a throw to cheer it up. Remove the heads and remount them on one wall, so they are more of a collection, not spread out all over. The honey color will help that orange of the trim to blend better and not stand out so much. Buy new curtains and hang them closer to ceiling height so the walls look taller as an illusion. They should be floor to ceiling long. Think the colors of fall leaves up north. Honey browns, oranges, beige and deep reds. It will warm it right up and play up the deer mount/trophy.

You are a good wife. My husbands mounts are in his office. LOL

Your decor with all the deer trophy's says a rustic cabin. The reclaimed wood wall suggested is a great suggestion. Remove the frilly curtains and replace with a lined fabric in a pattern and color of a woodland. Follow up with some colored sofa pillows chosen from the fabric. Take colors from Native American blankets, accessories of pottery, baskets, birchbark, pictures of hunting scene's, a leather chair , a rustic wood coffee table. The trophy heads should be hung a little differently. Try the two large buck heads over the sofa, side by side leaving room between them for the two small ones one over the other in the middle. Start with something and the rest will follow.
