What colors are your furnishings? How about the flooring? I am having difficulty following the colors. You are adding Sheetrock? Where it is currently green? It appears that your kitchen cabinets are black, with brown/white tile going part way up the wall? I would avoid all grays and go with something brighter and cheerful. All of this depends on flooring and furniture. No gold paint ( unless you are Steelers fans). Maybe white will be your best choice.

I do like the shutter on the top window. You can get cute ones with cutouts. Revere Pewter is a great color. I've used it in my house for walls and trim. Depending on how much contrast you want, it looks good with Copley Gray, Amherst Gray or a darker shade, Kendall Charcoal. Shown is Kendall.

The grey fad is essentially over; and since you are looking to brighten up the space, I suggest using a warm white. There are many warm whites to choose from. Benjamin Moore’s Ballet White is a nice, versatile color. You could try a sample. You could do the walls and trim in same color with different finishes. Or with the Ballet White, BM’s White Dove would be good on trim. I like BM’s Natura line.

While we wait forthe paint gurus, my only suggestion would be to paint the house one color only. not a fan of two tone for this style home.
