Franksmom, it's BM Mellowed Ivory. My trim is the lightest color on the strip. Pal and Sparkling water, my subtle hint detector isn't working. I know you haven't seen the coral bedcover (It's a carved velvet and the carved-out parts have a green and ivory stitching in them), but are you suggesting that coral walls are a better choice by more than a slight amount? Or is coral an option of similar value? I was concerned about the wood tones. The case goods are the nicest thing in the room and I usually feel more comfortable with more contrast between the wall and the wood furn. Also, the walls in the rest of the house are shades of yellow . Here is a link that might be useful: BM mellowed ivory

What brand and quality is the piece? Mahogany has a natural reddish tone, trying to change that will probably ruin it. If you strip and restain the piece do you have that ability to put the french polish (lots of work) back on? There's nothing wrong about having different wood tones and furniture styles in the same room. Matchy-matchy is boring.

I can’t find the inspiration picture, but they normally don’t provide details. If you search wingback upholstered beds in the Google Shopping tab, you can view a lot and easily compare. Click on See More when you get to bottom of page. My son and his wife bought theirs on Wayfair and are very happy with the quality. Important to read reviews. I found one on Joss and Main just to give you an example and they have lots to choose from, with reviews as well. https://www.jossandmain.com/furniture/pdp/bellaire-queen-upholstered-platform-bed-j001022256.html

The maple looks good with both the wood floor and the kitchen cabinets in all the photos, and it fits the Scandinavian aesthetic. It also offers a lot of contrast with both the cabinets and the floor. The only place where I think it isn't a clear winner is in the bedroom, where I think the walnut (bottom left most pics) looks better with the color of the carpet. The two mid-tone warm woods (in the middle in most of the pics) seems too close to your floor color. And the warmer of the dark samples doesn't fit the aesthetic. I appreciate your attention to detail in evaluating the samples in all the rooms in different light. People routinely underestimate the impact that light has, and I've found that when I'm evaluating samples, my favorite can flip back and forth depending on the light. And then you are asking yourself, when am I going to use the room the most, and should I go with (for example) the color that looks second best all the time, or the one that looks the best in natural light during the day but ranks far down the list under artificial light in the evening?
