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.

Is your plan to pain the entire house or just the trim? On my monitor the current color is yellow with a set of burgandy shutters and a set of green shutters. Green trim. Is this correct?
