You have four previous paint posts. If none of those ideas work for you, try priming it all with two coats of white primer, then get your upholstered furniture and choose a light neutral that does with their colors.

It is hard to pick colors when you have green and purple reflections on your samples.

Gray is on its way out in some areas, YMMV, but if you want gray for now, pick a light warm gray that goes with your warm hardwood flooring. Cool grays will not work well with the flooring.
