Hit Polish describes the glitter in 'Retro Chic' as "fine pink, fine silver, fine cayman blue, matte aqua hex, small rose hex, medium rose hex, small aqua matte hex, small gunmetal hex and a touch of fine black and small black hex". The base is clear.
In these photos, I'm wearing two coats of 'Retro Chic' over yesterday's Color Club 'Status Update'. I liked the combination, although the fine black glitter gets a little lost because 'Status Update' is dark. The glitter didn't give any trouble, but I still topped it with two coats of Gelous for ultimate smoothness, and one coat of Orly Sec 'n' Dry top coat.
The clear base is somewhat thick, to keep the tons of glitter suspended, so Rachel mentions on their site that you can use nail polish thinner to change the consistency if you like. I found that the consistency made it easy to control, so I did not thin it at all.
Hit Polish, made by the husband and wife team Don and Rachel of D&R Apothecary, has awesome glitter toppers. Their tinted base polishes look great, too (especially Tea-Stained Linen; I want!), but I haven't tried them yet. Their full size polishes are typically $8.00, and the mini bottles (7ml) are typically $4.00, but they often have sales. You can purchase Hit Polish from their Etsy shop: http://www.etsy.com/shop/DandRApothecary.
Thanks for reading! Do you have any favorite glitter toppers?
