Combine crushed pretzels, sugar, and melted butter in a large bowl.

Mix well until the mixture is evenly moistened.

Press the pretzel mixture firmly onto the bottom and sides of a 9-inch pie pan to form the crust.

In a separate large bowl, combine sweetened condensed milk, lime juice, tequila, and orange liqueur.

Divide the mixture into two equal portions.

In one portion, add sliced fresh strawberries and a few drops of red food coloring.

In the other portion, add a drop or two of yellow food coloring.

Gently fold 1 cup of whipped cream into each of the strawberry and yellow-colored mixtures.

Spoon the strawberry and yellow-colored mixtures into the pretzel crust, alternating colors to create a marbled effect.

Freeze the pie for at least 4 hours, or preferably overnight, until completely frozen.
