this is a problem with open floor plans.

you do the space in between neutral or a blend of the two bolds, and make sure the bold colors are ones that play well together.

i have this situation with living room/ dining room/ library in a row with large openings between. i solved it by having a paper in the dining room that contained the colors from both adjoining rooms.

Although not today's concept of open floor plan, my older house has each room open to the next separated by double doors. I hate neutral or white walls and crave deep colors. I printed a floor plan of the house and painted the colors I wanted in each room to see how they played with the adjoining rooms before finalizing the colors. There is no need to repeat the same color in another room you just want them to coordinate or contrast well with each other. Most paint lines even offer coordinating suggestions to help with this process.
