The past tenant painted the basement a myriad of colors. The living room is lime green and the in-wall shelves are burgundy. The kitchen wall is a mix of burgundy and yellow. The bedroom is yellow. All the baseboards are white. I want to choose more neutral colours such as light beige, eggshell, etc. However, I want to make the basement brighter, mature and not look lived in by a teenager. Any suggestions what colours to paint the wall so it will look classy? Should I also paint the baseboards a complimentary colour other than white? Should the ceiling remain white?
