Get real here. Do you honestly intend to take advice from any of us, when all we have to go on is a vague description of your cabinet colour, and what those tiles and paint samples look like on our computer monitors???? As always, my advice is to get yourself a colour wheel, and a fan deck of the paint brands you are considering. You need to analyze exactly what the undertones of your "creamy white" cabinets are. I'm not seeing enough to know if a "warm" colour will work in your kitchen or not. It's always better to chose a colour that "works", than spend the next few years wondering exactly what went wrong.

I like the idea of Manchester tan especially since you already know that warm neutrals suit you so well. I wouldn't go too light on the paint color, especially since it doesn't get alot of natural light. The slightly darker will give you a nice contrast in low light. You might try a large scale sample of the Manchester tan and see if the undertone agrees with your countertop. From looking at other pictures of rooms painted manchester tan on the web it looks like the color can run a little cool. IMO, I'd stay away from paints with green undertones. What is your countertop material? BTW, love your cabinets!

This may be too late but in case you haven't picked a colour yet have a look at BM Collingwood. It is a nice gray that is not too cool nor too warm and may work well with your countertop.

You desperately need some COLOR and more natural materials here, to balance out all the gray overload. With all of those cold tones, you need to stick with a cold color, like a blue or lavender. Warmer clors would only clash. And, since everything is the same medium value, you need something DARK and saturated, to create some dimension. Think a navy blue, or deep plum.
