Decorating Dilemmas

I am having a lot of anxiety with this decorating project we have decided to undertake.

We did the laundry room a lime green (see picture above) which is great and what I wanted.

The laundry room is on the main floor and now I want to do the open concept aspect of the main floor - kitchen, dining room, hallway, family room and pillars.

What colours do I choose that are not going to completely clash with the laundry room?!
