01 - In a medium bowl, combine strawberry or cherry gelatin with 1 cup boiling water. Stir thoroughly until dissolved. Add 1/2 cup cold water and mix well. Evenly divide mixture into 8 small clear serving cups and refrigerate for at least 1 hour or until fully set.
02 - In a separate bowl, whisk together vanilla pudding mix and cold milk for approximately 2 minutes, until thickened and smooth. Gently fold in 1 cup whipped topping. Once the red layer is set, spoon the white pudding mixture evenly onto each cup over the red layer. Refrigerate for 30 minutes.
03 - Dissolve the blue gelatin in 1 cup boiling water, stirring until fully dissolved. Incorporate 1/2 cup cold water and stir to combine. Once the white layer is firm, gently pour or spoon the blue gelatin over the pudding layer in each cup.
04 - Refrigerate assembled cups for an additional 2 to 3 hours to allow all layers to set thoroughly before final garnish.
05 - Just before serving, top each cup with additional whipped topping, fresh berries, and sprinkles as desired.
