@Avery I did a very poor job of lightening the trim color, but I think you will get the idea. I think a warm off- white would look so good, like the inspiration picture. I would see if SW Shojji White is too light and go from there. SW Alabaster is also a beautiful exterior white. BM Ballet white. BM Dove White, BM Sea Pearl are all great exterior whites without being stark and cold. Paint a few samples on large boards and see it outside next to the wood and the brick.
I would also love to know if the garage door could be sanded back to a more natural color, and sealed with a clear coat. It would be stunning!
