Love your tile. Do you have dark wood cabinetry under the sink there? Palladian blue is soooo pretty. But "golden straw" sounds nice too, especially if you have other colors in there. A dark turquoise might be a bit intense for a paint, especially if you do paint the ceiling the same color (which I've done in my own bath and it is great, makes it all very subtle ...) and as it seems to be a narrow space. What other colors did you want to use? Like in your towels especially. I could imagine a palladian blue paint or a soft gray and several shades of deeper blue towels, maybe even some grays too.

Is the current color too light? too dark? The carpet will narrow the undertone hue--yellow? pinkish? Good all around Benjamin Moore colors: Manchester Tan, Maritime White, Bone White, Shaker Beige, wood ash....

Then have that colour mixed in washable matte. The contrast in finish between the wall and the trim will look interesting. White will show off your kitchen beautifully and you can add colourful artwork/accessories.

That makes we want to leap in there with paint of ANY colour and paint from ceiling to floor. Oh dear, not good, hey? I suggest you get a colour expert to try to identify the white on the cabinets, which presumably has some or other undertone, identify the colour, and go just a bit darker -- one or two samples down on the colour card. And paint the walls top to bottom that colour. Actually, this redo looks like real fun. It's going to make such a difference. May I suggest you get rid of that key pattern on top of the cabinets? It's really meaningless. Not beautiful, not functional.
