Consider Grey or white. U could also use geometric or any pattern in mint green

Teal is a very trendy colour, but having it on all four walls may be an overkill in the kitchen, especially with that dramatic chevron dado tile. I hope at least the 4th wall is white! The cabinets have to be white too

The potential yellowness discernible in Simply White is because it is actually a more colourful white from the Yellow Hue Family. That little kick of colour can work well on ceilings, as that plane can often make a colour appear a little darker & more greyed anyway. So sometimes a choice of more neutral greys here have a possibility of ending up a little grey & shadowy. This is obviously dependent on the available light. Chantilly Lace is a more neutral white from the Green Yellow Hue Family. In character in balanced light it can appear ‘just white’, but in some light people see a hint of its inherent greenness, some might even read it as blueness. Again depending upon how well balanced the available light is. Super White OC-152 is that bit more neutral & so could read a touch more crisp again. Many people prefer a more neutral, crisp trim. It can give you more options for alternative wall colours, should you decide to repaint down the line. Neither Simply or your trim choice would be sat next to each other though, as the wall would come between them. I think the biggest concern would be sitting Simply White next to Classic gray for the reasons mentioned before. If you are set upon Classic Gray then I would repaint the ceiling and swap to one of the more neutral options. I would shortlist your line-up and sample upon board or lining paper in your space so you can move them around.

Hi Idsshyam, For beige walls, white tiles/marble are a classic pair. This gives you a blank canvas to work. You can also go for darker wood tones such as mahogany or ebony flooring to contrast the lighter wall colour. A cool-tones beige would also complement maple, birch or walnut wooden floors. These can easily bring a contemporary look to your space. Hope this helps. Good luck with your home design.
