What I want to know is: do the same people who name flowers also work for the folks who make paint? are these jobs seasonal, so you can do them in rotation? is there a special school to learn arcane and delicious words that describe nothing and evoke everything? Misty Twilight, Exotic Life, Morning Mood, Warm Welcome--which are flowers and which are paint chips?
