I painted the exterior of my house in SW Pure White - it's definitely on the bright side of the white spectrum.

We just completed a bathroom remodel, all white color palate, some variations if you really analyze it, pretty tough to match up entirely.

Definitely get swatches and test for it.

Post the kitchen pictures, as is........and what is the flooring? Add all in a comment box, from several angles

Yes please do not start another post.

Take a sample of the counter into the SW store. They can scan it and tell you what colors are closest. They can also give a color match in one of their products if the cabinetmaker is using a SW paint. Ask them.
