I find Serge Lutens Gris Clair to be a bit melancholic, and I think it is a scent that works in well in both fall/spring. I may be alone on this one, but to me this excellent lavender is a bit cold and smoky.
You're not, I was going to write Gris Clair, too! I find it very meditative. That reminds me, Dzongkha is a bit melancholy, too.
