I had roughly 40 samples, all different colors, shapes, sizes, etc.

What color would look good?

I ended up having a couple self imposed delays on things like materials, colors, finish items that could have been avoided by better up-front planning.

If so, any color recommendations?

@Karen Margrave @Bryan Hancock Bryan is the real trail blazer thus far.

The old paint is still in the garage, so I could make those repairs myself, but I know it wouldn't look nearly as nice as a professional repainting job.The kitchen/dining is painted a horrible BLOOD RED color.

You might be well into orders for cabinets, flooring, & appliances by the time someone asks about options (wink, wink), but now they're interested and maybe you could squeeze in a different backsplash or paint colors.  

Will obliterate smells, dont put on stuff with colors, but your concrete problem will be fixed

This will add color and make the home more attractive.Third, prepare to drop the price more.
