Have you met, or even seen the bride-to-be? Years ago someone told me that if I want to gift someone and don't know them well, check out what they wear. Women, if they have the means, wear and decorate their houses in tones they feel enhance themselves. It's automatic. And he must like what she likes, right?
Having said that, I have to tell you that the idea of having "neutral" tones used on a wedding bed sounds out of kilter to me. That's one place where it should be a bit lively. Anyway, check HER out.
