Sherwin Williams is a decent paint. I have used both it and Benjamin Moore. Personally, I will never buy Benjamin Moore again, but many love it and use it all the time. You also need to be aware that bases are different for paint brands, so you may not get the same exact color in another brand, so its better to go with the Sherwin Williams. Reviews are not always accurate. A paint job depends upon the prep that goes into the project. Also what kind of paint is on the wall right now. Is it the type that needs a primer? Flat paint is less washable than matte. Matte paint is less washable than eggshell. Eggshell is less washable than satin, and etc. The sheen you pick is dependent on whether you have little ones that often put hands on walls, and will need to clean it often. It is also dependent on the condition of your walls. Anything with a sheen will show wall imperfections more. Flat or matte, will not show the imperfections so much. Also, I would want some type of washability in bathrooms and kitchens and in my case, my hallway, which always seems to have finger prints for some reason.

I've been looking at high end roofing tile websites and one of them has a color expert that made recommendations for house paint colors with their orange/brown roof tiles. Here is a link to some of the schemes they recommend that may give you some inspiration: https://www.davinciroofscapes.com/blog/exterior-color-schemes-autumn/ You can color match to Sherwin Williams brand paint.

@Lori...any thoughts on what paint colors (preferably sw or bm paint) I might want to peek at that are very similar to Accessible Beige as I am picking up a very slight pinkish/purple-ish tone that isn't completely desirable... perhaps something a touch to the right toward yellow hue on the color wheel but a similar chroma and lrv??

"One also mentions an ultra white base. I’ve heard base can change the tint." Absolutely can and does make a huge difference. That is why if going with your method of buying it a gallon at a time, you absolutely need the same paint line and have started with the same base. Even then there is no guarantee that the colors will match perfectly.
