It's really hard to come up with a suggestion without an idea of what you like, or how this room relates to anything else in your house, or even a far away shot showing the whole room. Are you looking for a suggestion for a less in-your-face shade of yellow? I"ve read that the best yellows on the wall look muted on the chip. Maybe BM Navajo White or BM Gentle Cream?

Can you post pictures of the entire kitchen from further back so we know what you entire kitchen looks like, not just bits and pieces. We also need to see the floor.
