If you do a search for the color name and click on "images" on the search page, you'll find some rooms that others have uploaded that are painted in those colors. IMO all three have a pink undertone which can be difficult to work with. Beware the dreaded pink undertone. :o)

You are being WAY too hard on yourself. It looks awesome and you picked exactly the right backsplash and grout - no easy feat. The bit of granite would be a problem if the backsplash was not quite right, but since it is you're fine. Trust me - anyone who sees that kitchen will just think it's beautiful. I do!!

Load this one onto the Sherwin Williams site where they have an app you can play with to see the different HOA colors actually on the house.

Sorry I didn't have the opportunity to answer last night. I think that your stone looks much less warm because of the beige currently next to the stone. Color is never isolated, it plays with the colors surrounding it. It is also better to look at color from a bit of a distance. To make your final decision, use the painted samples that you have and tape them 2 at a time to the garage door. Step back, decide which of the two you like best and then replace your least favorite with your next sample. Leave a bit of distance between the two samples. For neutrals, because their undertones can be so sneaky, I paint large samples. 12x118 or larger. I like to use 140 lb watercolor paper - it doesn't get warped and has a nice tooth to it. If it is a bit curled I place a piece of parchment over it and iron it flat. https://www.michaels.com/canson-xl-watercolor-pad/M10145805.html I would also suggest reading a review by kylie m interiors on SW gray-greige. https://www.kylieminteriors.ca/sherwin-williams-best-gray-greige-paint-colours/ Always find her advice on paint colors to be dead on. To do my own evaluation of your stone and paint colors I took a screenshot of the stone and copy/pasted it into excel. I then pulled the RGB values from the SW web site. I entered those numbers into Easy RGB and took snapshots of the convert page from Easy RGB for each color and placed it next to the stone screenshot. . Of the samples I personally like Modern Gray and Wordly Gray. I love Versatile Gray in the photo, but I tend toward taupes which means that this could go pink. The hue measurement shows that It is on the brink of having pink/purple undertones. Please understand that every computer monitor is different, so machine comparisons are never as good as real painted samples, but it can give you direction. If you like something but it is just a bit off you can use tools like Easy RGB to find a similar color that is just a little lighter, a little less green or a little more gray.
