Fill Cocktail Glass with Ice. Pour in the 1 oz. of Peach Schnapps, then add Orange Juice 3/4 to the top and shake. Slowly add the 1/2 oz. of Grenadine Syrup (watch it sink to the bottom of the glass). In a Mixer, Mix the 1/2 oz. of Blue Curacao with the 1/2 oz. of Vodka then, slowly strain into the Cocktail Glass (filled with Orange Juice and Grenadine Syrup). Voila! Your inverted Traffic Light. Note: The drink is consumed in layers and therefore, not stirred.
