77 is an olive green lacquer packed with golden shimmer. The formula was wonderful and application trouble free - very nice for a cheapo polish! Guppy is a Korean brand and not widely available outside Asia, but can be purchased from the seller jolieeeee on eBay for under two euros each.
SpaRitual Optical Illusion is murky olive green glass flecked jelly with two nearly identical siblings: Orly It's Not Rocket Science and China Glaze Zombie Zest. I found the Orly slightly more saturated and "prettier"; I don't own the China Glaze polish and thus cannot compare the two.
