Waht???? How are you seeing the samples?

If you're looking at colors on a computer monitor, you can't judge undertones that way. I suggest you contact Yorktowne directly and order finish samples for any or even all of the following:

Buff

Chai Latte

Cottage White Sheer

Divinity

Irish Creme

Magnolia

Sea Salt

White Icing

Look at the samples under real-life lighting conditions, in the room where you want to install the cabinets.

This ^^^^.

Why are you limited to Yorktowne Cabinetry? There are a plethora of cabinet companies out there, to consider.

"Divinity" York towne with Greek Villa..........

Is that a guarantee? No. In person is the only guarantee, but that's the closest I can cobble from their website

First???

The very first thing about a build, or a redo of a kitchen is your layout.

Show that!

Layouts/function first , is driven by your appliance selection and the storage you require

What will be the flooring?

What do you plan to use for a counter top?

Know that if you plan a quartz top? You will find the whites are not as "soft" they are cooler and brighter.

Once you have settled on all above, and Gotten an entire plan together, you can verify a specific white........

With a question as you posed, nobody here can answer . Given all the "highlight options " I am seeing on Yorktowne whites? They seem to be a wide selection in color and stain.. Just saying........: )

Best would be to find a dealer in your are, and see samples in person,

Not a lot of white inspos on their site
