I also have Hustle, and was a bit worried when one blogger's photos showed it leaning very mustard coloured. It is indeed chartreuse, as your photos show, but I'm finding my swatch looks mustard in natural light and chartreuse in artificial. So strange how polishes can do that! I like it though, as I think the mustard and the chartreuse are awesome looking :o)

I don't get too many tick or treaters usually, (depends on weather) but I do like to see the kids in their costumes, especially the little ones (so cute!) and sometimes clever ones (there was a young girl who was Dark Helmet from Spaceballs last year! How awesome!)
