IMO if this is anew build go with one colr everywhere that is as neutral as possible because IMO paint color is the last thing that should be decided . I have no idea what the spaces are you show and bedrooms are best done to go with bedding and adjoining bathrooms best to coordinate with bedrooms . Tile colors flooring , cabinets , counters all have a bearing on wall colors .

Do the changes of color relate to the light exposure in each room? Which plan is the family's favorite? Have you sampled the colors in the rooms? If not, get sample pots and big white poster boards. Paint a sample in the middle, leaving a large white border so the current wall colors don't interfere with what you're trying to see. Move the boards around to different walls at different times of day and in different weather conditions to see what they'll look like in your home.

I agree with Patricia. We painted our whole house beige in satin for scrub ability. And then as we decorated each room, we repainted.

HI -- Why are you making this so complicated ? Not every room needs to have a seperate color . So many colors makes it very expensive in paint and labor . If you did one basic color throughout then you could get contractors 5 gallon paint pails and that would be cheaper to do and not complicated and easier for touch ups . The ceiling doesn't even need to be different from the walls either depending on the color choice and style of the house, if it's Traditional or Modern .The interior will look much fresher and current and will stand the test of time if you had one color throughout . So many colors is not the way interiors are done now .

Thank you to all who replied. I'm definitely starting to feel the decision fatigue of this house building process.

As decoenthusiast suggested, I did buy samples and move them around. It was my preference to have some lighter neutral colors on the wall like Patricia said. I should have mentioned though that as the mother of three young kids, I tried to pick a shade darker than was my personal preference so that it closely matched the color of fingerprints I knew I'd find on the walls. In areas where I thought I could have the lighter shade I wanted, I did that. I did try to think about using the same main colors in several rooms so that at least some 5 gal. buckets could be used.

The rooms with all the crazy colors are for my kids and I did let them pick their own colors to match the bedding they've already picked out. So while their rooms may not stand the test of style time, neither will their tastes and I'm sure I'll have the chance to help them repaint them as they grow up. :) I've provided the room's purpose on the reattached images. I should have thought to include them before

Looks good!

I think your color choices are really nice and all compliment each other well. Most of these colors are pretty neutral so they will go with any decorating style. Well done.
