Place the cookies in a ziplock bag and seal. Using your hand, or a rolling pin, crush the oreos until they're in small pieces. Set aside.
Using an electric mixer, beat the cream cheese until smooth. Fold in cool whip and continue to mix until smooth.
Mix in vanilla, salt, and lemon juice.
Take out 1/3 of the mixture and set aside.
Add yellow food coloring to the remaining mixture and beat until full incorporated. Add as much as you like to get the desired color.
Take out 1/2 of the mixture and set aside with the white mixture.
Add red food coloring to the last bit of the cheesecake mixture to make orange. It won't take much, the red is usually very potent!
Once you have your white, yellow, and orange cheesecake mixtures, you're ready to assemble!
Spoon 1/4 of the cookie crust into the bottom of a glass. Top with yellow, then orange, then white. Repeat for the remaining three glasses.
Top with more whip cream if desired.
Enjoy!
