grays are definitely tricky, and very dependent on the light conditions in the space. take your Sterling chip and go back for something several shades bluer -- get a range of samples and paint them on your wall or on large posterboard that you can move here and there to see them in context. that's the only way to choose.

If you did not see blue what did you see? Did it look off white? Or pale gray?

It sounds like the color is not deep enough for you but also not blue enough.

Sterling has an LRV of 62. You could probably go as low as 55 without feeling it is too dark. Glass Slipper is brighter with an LRV of 70 and it is bluer.

I think you should return to the store and get a lot of the paper chips to tape on your wall. After you narrow it down a bit you can buy a sample.

If your wood cabinets are light to mid tone, they probably read "warm". It can be hard to mix warm wood cabinets with cool grays. Instead of looking refreshed, the kitchen can look drab. Try colors above in sample jars, but if it is not working, look for a warmer option. So many of the kitchens features are cool white or darker wood and it is difficult to get an inspiration if your cabinets are mid tone.
