That's an interesting question. I'll be curious to read the responses. I used to think of No. 19 as a bit cold back in the day. I haven't sniffed it for ages, so I may not think so today. I think of some other green fragrances as a bit on the cool side, like Ivoire and Paco Rabanne's Metal. Estee Lauder Pleasures is a bit cool, which might be why I enjoy it most in summer. I agree with you that Cristalle (edt) is a bit austere. I like that about it.
