jane ny, I was in a similar situation last year. For me the sequence was paint first, then flooring, then baseboards, But it looks like you may have baseboards already installed. Painting first worked for me because I did it myself and there were spatters on the subloor before I was finished. You might want to check on whether your subfloor is indeed covered with plywood, because you may need an underlayment before installing your floor, depending on what you choose. Best to check where you buy the flooring. With some help from a friend who knew what he was doing and owns a Skill Saw, I installed a plywood underlayment in less than two hours. I too wanted tile with a slate or similar look, but the room was already over budget (long story) and I chose to spend my money on high end French doors because the floor could always be changed later. I got some advice from the flooring forum while deciding. You can always post a message there before you proceed. We narrowed floor choices down to either loose-laid sheet vinyl or vinyl tiles. My friend chose the tiles because the color and pattern seemed to fit well in the sunroom/porch. The original intention was to keep those tiles for about a year while I shop for tile and find a good tile installer. But the floor has held up well, despite some abuse like beach sand, rain coming in when some airhead (

It does look a little muddy to me as well. My sunroom (which is our playroom/family room) is painted BM Summer's Day (CSP-780). I really love it. It is a similar color but brighter and more saturated, I think. Here are a couple of pics. Prior to drapes going up: With drapes:

Well, I am still battling one! I was dumb enough to release one that I caught and it just came back in and brought a friend. I have now sealed the area where they were coming in, so no more should be able to squeeze through. Yesterday I caught one in a trap like yours bacon - no more mercy! There is one left and I got these new traps that came this morning, I’ve just not had time to set them up.

We need a little more info but first IMO you need some sort of heat and light blocking so solar shades would be a nice choice and a floor plan with as much detail as possible like the measurements of all the spaces and doorways for sure . Is the sofa staying, is that a good indication of your style. Some pics of the other spaces in the home would be helpful
