In the 1920's when neon signs were first displayed in the U.S., people were drawn to them for their brightness and unique look. They began to call the signs "Liquid Fire" because of the ruby red glow they cast. When I put on Sinful's polish in Merlot, I was reminded of the beautiful glow of these long lost signs...the original ones from a bygone era, not the mass produced ones of today's market. Sinful has a great range of colors and can be found at Walgreen's, among other places, for $1.99. I absolutely love this color...a true ruby red with just enough shimmer to give it that "glowy" effect.
