I don't think painting the bottom a different color is a good idea. Two me it looks like a layer cake. The current color looks like pale gray or beige. I would give it white to stand out better. I made these images on the SW site so they are sloppy. I did not change the door color, it just looks black, I like the current color. I don't like the previous owner's landscape and hard scape designs. One thing you could change is removing the gravel. It looks like you live in a hot area and the gravel is giving a harsh, barren impression. Mulch would be better and in time most of the beds will be filled with plants. I found a picture of decent landscaping on a ranch house. What is your growing zone? Which direction does the house face? If it faces west or south you might consider a shade tree.

I too came close to using Watery for my front door. But you can end up losing color by about a third outside. So I went with Drizzle. That is light color enough, but behind my screen door, it does exactly what I wanted :) I also came close to using Eider White for the trim. I feared it would end up too bright against my somewhat warm brick though. So Aesthetic White was a great compromise without veering warm. Eider White could work for you though, with whatever gray or greige you choose! Here’s what Eider looks like :)

I tried selecting a color from the stone to use for your trim, but you can see it turns into a muddy mess. If the stone is to stay, I would consider using a limewash on it to make it more 'neutral' and less gold in its appearance. Then once you lighting the appearance of all the stone, I would paint all your trim a grayish white. Here is another example of limewash used on golden stones

I think this is attractive combination that looks good with brick, which I would not paint. If you want to do do only one color either LaPaloma Gray or Winter Orchard works. Bachelor Blue looks good with the roof. Please trim the bushes so that they are no taller than the bottom of the pretty windows.
