I've always heard the configuration termed a 'Winchester'. Like this? Cocktail cuff, turnback cuff, James Bond cuff, Neopolitan cuff, etc... I have actually heard a different origin for the white collars/cuffs on a colored shirt. The story goes that upper-class gentlemen liked the look of the colorful patterned shirts of their lower-class brethren, but it wasn't considered 'proper' to wear colorful shirts in polite society. Solution: Colorful shirt body, 'proper' white collar.
