Here is a photo...Obviously the lights need to go.  

You can also assume numbers for the kitchen, baths, mechanicals, lighting, appliances, etc.

I have a house I plan on rehabbing and the roof color doesn't go well with the rest of the house.  

Naturally we’d need some specialized training, he said – then the lights went dim.

Yesterday I went to get Allure at HD for a property I'm getting ready, no problem on the cherry plank, bye the Ahlar I use in kitchens and baths is out and was told its discontinued along with Corfu, the Sedona color was still current, but I don't like the look as much.

I even threw in some premium things not found in any comps (LED can lights and quartz counter tops; they didn't cost me any more than normal stuff would and they look great).

For example, if a contractor has extra cans of paint, light fixtures, etc. after completing a project, they would donate it HfH.

You join the spreadsheet (table) to a geometry (property boundary, blocks, etc), then you visualize the data with a logical color scheme.

Between that and personal service as @Michael Boyer mentions, paint colors inside, etc, it is pretty easy to differentiate yourself from the big management co's.  

From the photo the roof just looks like a standard grayish colored shingle roof which in my mind would go with any number of siding choices/colors :)  Just my two cents.
