Paint color depends on style of house. 

Someone scrawling all over the accent wall you put up so many color swatches for to find the right paint?

@Karim Wahba, to add a little color to Chris's comment: the typical syndication costs between 10 and 15k to setup.  

Most of them are $10 or a bit more with extra digital items included, and it's very easy to add your info, brand the colors and then upload it to Dropbox.

2) How important is it to have a variety of colors throughout the home?

Painting houses a neutral color is the easiest and least expensive way to get houses rented or sold. 

Or keep the uppers and lowers the same and contrast the island color. 

All foreclosures are based on gross fraud, forged signatures,fake documents, corrupted judges who are criminals working for the bankers.The same goes for the attorneys.This country doesn't have the lawyers, and public officials are not following the law.Not the common law not even their own fake, UCC code color of law.BAR attorneys are foreign agents trained to destroy American people and American Constitution!

As long as you follow the rules like lawn maintenance, paint the fence a certain color, keep the house a decent color you'll be fine.

I ask them on paint color, hardware, floor stain/finish etc.
