I stumbled upon this post when I was looking for aqua and red kitchen color schemes. (theletteredcottage.net)
I think most people prefer a warm white for cabinets since it is such a large part of kitchen color scheme and cooler colors can make a room feel stark if there is alot of it everywhere. (hersite.info)
We have a red toaster, so it's also nice to have some continuity to the kitchen color scheme. (oatmealwithafork.com)
