Beige is a problematic color for walls in that no two people will agree on exactly what it is. It can be the most docile of neutrals and it can be as insipid as a flesh tone. Beige is used as a neutralizing hue in between stronger hues but most often it is used as a safe compromise…
That perfect beige you picked out in the store will shift to “pinkish” on your wall because of metamerism. You did not see the “pinkish” cast of the beige at the paint store because the cool fluorescent lights cancelled that hue. The coolish Northern light coming in through a window makes the beige look perfect during the day but as soon as the warm incandescent lights come on… the pink pops out again.
