In a medium bowl, combine 1 cup of warm milk, 2 tablespoons of sugar, and 2 teaspoons of yeast. Let the mixture sit for about 5-10 minutes, or until it becomes frothy.

In a large mixing bowl, whisk together 3 cups of bread flour and 1 teaspoon of salt until well combined.

Gradually pour the frothy yeast mixture into the flour mixture, stirring with a wooden spoon until it starts to come together. Knead the dough for about 10 minutes.

Divide the dough into two equal portions. In one portion, mix in drops of red and blue natural food coloring.

Grease a large bowl with oil, place both portions of dough inside, and cover with a damp cloth. Let them rise for about 2 hours.

Punch down the dough, roll out both portions separately into rectangles, layer the colored dough on top, and roll tightly into a loaf. Place seam-side down in a loaf pan and let rise for another 30 minutes.

Preheat your oven to 350°F (175°C). Bake the bread for about 30 minutes or until golden brown and hollow when tapped.

Allow the bread to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
