Paint a big swatch of the paint you are using and bring home or order LOTS of samples. Check the out under the same sort of lighting you plan to use in the kitchen. White is hard to match because you have the "undertones" to consider Here is a link that might be useful: The undertones!

I just painted my bedroom and master bath SW Alabaster with SW High Reflective White trim and doors. I LOVE the look, both colors work beautifully together. Depending on the time of day (morning sun) it looks white without being too stark white, as the day progresses it warms up turning into a vanilla cream in the evenings. My bedroom is west facing with more windows and a small south window. My master bath is west facing. The High Reflective White stays pretty true to color at all times. Unfortunately they were not able to do the cabinets in HRW as the paint I used on the cabinets could not be mixed in that color. HRW is a color that is funny at Sherwin Williams and kinda' tricky and definitely takes more coats to cover. I used Emerald paint in Alabaster on ceilings, walls, and cabinets in different finishes and Super Paint in Semi Gloss in HRW for trim and doors. I was nervous about using Alabaster on the cabinets in the bathroom but it worked perfectly. I will say, for those that are using a white on walls that is not as warm as Alabaster/White Dove, or more cooler grays (think grays that aren't greige) the Alabaster or White Dove warm soft whites are going to go yellow/cream. I would recommend going with Pure White for cabinets and trim. It is still a soft white without the creaminess of Alabaster. High Reflective White is also a good white it's not as soft as Pure White but still not so white that it looks cheap, but again HRW is hard to cover and cannot be mixed in many sheens and paints. I decided not to go with Pure White with my Alabaster walls because my husband wanted more of a contrast with the doors and trim, I wanted to use Alabaster on everything, but made a compromise with my husband, and went with HRW. I am not at all disappointed with the look. I know I spent countless hours agonizing over the choices and hopefully this will help others that are in the same position.

I said on another post that i think Cloud White is highy underrated. I find it to be milky, but not creamy. More of a warmer white, not too stark, but not yellowish. They probably wiuld bith work with the colors you selected. I have cloud white with SW Contented and BM Carrington Beige and it works well with both. To my eye, white dove looks more creamy (yellow) in samples than it does in pics of people's cabinets. BM also lists them as coordinating colors. Your best bet is peobably to get large paped samples or sample pots of both to look at in the space once the floors are installed and cabinets are installed. Maybe one will jump out as the right one, but they will probably both work.

I would go with White Dove because of the warm tone of your tile floor. I'm concerned that Simply White might be just too white given the warmth of your flooring. Such hard decisions, I know!
