I have the same as you and also have 3 kids. I never worried about whether or not the rooms were the same; each kid has his/her own ideas about color, etc.

Now if you're talking resale, I would paint them the same.

Bedrooms get to be different! At least, I never thought they had to match...

Now, if you were mixing primary colors with earth tones, and one in neon brights, that might look mis-matched. But yours are not disharmonious at all.

To me, the most important thing is that the bedrooms each have a nice relationship with the adjoining hallway color, if possible...(kids rooms and their bright colors are the exception). I also consider the "enfilade" -- looking down the length of the house in a single-story home, making sure I have a pleasing array of colors.

What sweeby said lol (I'm getting lazy but she said what I was thinking)

Thanks, everyone. I now have to decide on a blue that is not too cool for the bedroom at the end of the hallway. It is situated at the northeast corner of the house, so it gets morning light form the east-facing window. There is also a north-facing window, so I would like a blue, but it cannot be too cool. ANy suggestions?
