I have just given you a magic wand. Cool, huh? Step outside and wave it over every bit of greenery you see. Say, “Abracadabra — I change you to beige!” Now peruse the result of your handiwork. All the life, vitality, joy and color have vanished, haven’t they? Now wave your wand again and restore the green. Does this make you think any differently about what constitutes a neutral color?
