Cotton Balls is a great color. It is a true white that is not stark or modern , but without being yellow, peach or tan. I haven't used it on cabs but I have used it on walls.

You should have them do a sample door and place it in your kitchen.

I don't think pictures are useful in showing such a subtle color -- the surroundings, the light, the camera, and the monitor could distort such a color quite widely.

It's kinda too late at this point to view this color in any photo or location other than your actual kitchen. "Creamy" is pretty subjective. I'd say my cabinets are creamy, as opposed to paper white. My white stove doesn't match, but I no longer care. It sounds like you did your research on the color and they will be what they will be. Everything will be fine.

I think I used Cotton Balls on my ceiling in my kitchen last year. it is a slight bit off white. It has a yellow drop or 2 if I recall. It goes great with my Titanium wall color which is in the white colors but is defiantly gray green. The lady at the hardware store, where I was first introduced to Cotton Balls, says it is her go to color for whites.
