Pour in gin, whiskey, blue curaçao, triple sec, and lime juice.
Secure the lid and shake firmly for about 15 seconds.
Place a strainer over the shaker and pour the drink into a chilled glass.
Add fresh ice if serving over rocks.
Notes
Gin adds herbal notes, whiskey provides warmth, and blue curaçao contributes sweetness and color. Adjust whiskey and lime juice for desired balance. Serve immediately for vibrant color.
