It reminds me of the painting by Vincent Van Gogh 'Irises' which shows several purple Irises and one lone white one.

I think I saw a film once that explained the reason Van Gogh painted one lone white Iris among many purple ones was because he was lonely.
I'm going to plant another Iris incase I become lonely by suggestion. I'll Feng Shui my garden.
