Which top?

Looking for your opinions please - which coloured top do you prefer on these light grey diffuser bottles?

Saw my first butterfly today, a wee tortoiseshell and S saw his first bee (I've yet to have that pleasure).

A long and busy day but making good progress. Looking forward to launching some new products next week but lots to do in the meantime, like actually making them, the photography and adding them to the website/descriptions etc
Also a wee bit of brand tweaking which I'm really liking (not shown here).
