What part of the country do you live in?

Pick out colors or whites like you want. Paint on poster board, or buy the peel and stick color patches and put on poster board. Leave a white border all the way around the poster board, so it doesnt clash with the color you have now. Since you want the whole house the same color, then pick a color that goes in your kitchen with your cabinets etc first. Then try it in the rest of the house. The color in there now, does not go with your cabinets. It has way too much yellow in it. I would look for colors that have no yellow hues.

You could take the tile to Benjamin Moore and let them use a color meter/detector/scanner to read the color of the spot on the tile you want to match and either custom-blend something for you or point you to the nearest match. Always get a test pint and paint it on a large board or sheet of something or the wall itself before purchasing the gallons. The sheen can make a big difference in appearance of the color. I recently did a couple of rooms in Benjamin Moore's Aura paint from the Affinity collection in satin sheen, and it was initially a little more reflective than I had wanted, but I love it now, and it's very easy to clean if needed. Aura is the most water-resistant of the paints and good for kitchen areas.

Yea it is confusing with the rendering. Sorry about that! The rendering is simply for house design reference. I notated what material is on what part of the house for help in what color should be put where. I’ve read that you’re supposed to use the same color on the same materials. Not sure if that rule is one to follow or not.
