We need pics to help.

Are you asking for a rug color? Or a tile to adjoin this one? If you are looking for a tile in the living area that can go next to this kitchen tile then post some photos of the spaces. If you have to use tile, I would try to find a solid light taupe that blends with the kitchen tile, but I think a better option would be to use one tile throughout all the spaces, or maybe put a hardwood in the living area.

Now that you have lived in the house for two years, you will have figured out if the kitchen foot print is usable. As soon as you start renovating this kitchen, you will be tempted to change things. Little things. Things that have bothered you for 2 years but could do nothing about. Once you do that, you have a new foot print. And then saving the boxes will be irrelevant or impossible (depending on how much of a change you make). Because change is inevitable, you will want to plan this out CAREFULLY. You will need to figure out your floor plan FIRST. Then you can look into whether or not it makes sense to keep old boxes vs. starting new for a full upgrade. If a bigger change is going to happen, you should get a certified Kitchen Designer on board. S/he will save you plenty of money with her/his designs and abilities. The KD will put together a package for you, including colour palette, flooring and counter top materials. Which you will direct the KD to order for you OR you can source yourself and then have installed. At which point, the flooring is decided WELL before the kitchen is touched. As you can see, you have a few more steps to go before you worry about flooring colour. To decide now, before you have a full idea of colour/materials would be putting the cart before the horse. Floors go in last (and can be chosen last). It is an important thing to work with. As tempted as you are to get rid of the red vinyl, you will be very upset to pay for a floor TWICE (which is often the case if flooring is changed before the kitchen is renovated). Because you have vinyl that is EVEN with the hardwood (same floor height) I would look at very thin product. It will prevent a large 'lip' from occurring through the doorways. But that's a decision that can come LATER. Right now you want to figure out the kitchen's footprint.

We have hardwood throughout our main no tile at all. Is that an option ?
