01 - In a medium bowl, thoroughly dissolve the red gelatin in 1 cup boiling water. Stir in 1/2 cup cold water. Evenly pour the mixture into 8 small clear cups. Refrigerate for at least 1 hour, until fully set.
02 - In a separate bowl, whisk instant vanilla pudding mix with 1 1/4 cups cold milk until smooth and thickened, about 2 minutes. Gently fold in 1 cup whipped topping. Once the red layer is firm, spoon the white pudding mixture evenly over each cup. Chill for 30 minutes.
03 - Dissolve the blue gelatin in 1 cup boiling water, then stir in 1/2 cup cold water. Once the white layer is set, slowly pour or gently spoon the blue gelatin on top to cover the previous layer.
04 - Place the cups in the refrigerator for an additional 2 to 3 hours until all layers are completely firm and set.
05 - Just before serving, top each cup with more whipped topping, fresh berries, and sprinkles, if desired.
