Everyone, tell me what troubles you had during the decoration process?

Should the living room use warm colors or cool colors? My wife prefers warm colors and feels that they have a warmer family feel, but I prefer cool colors because I think there may be guests coming to the living room. If it is made in a pink color, I may feel that it is so... One point, shouldn't it be a silver or white, more formal environment? We argued about this for a long time, and finally chose a light blue as a compromise, thinking that this could combine the opinions of the two people.
