Mix Greek yogurt with half n half, simple syrup, and vanilla.
Divide mixture, with ¼ in one bowl, ¼ of it in another, and the remaining ½ in its original bowl.
Mix orange food coloring into the large bowl and yellow into one of the small ones.
Pour yogurt mixtures into separate zip-top bags. Cut a hole in the corner of the white bag, and squeeze some of the mixture into the bottom of each mold.
Squeeze a lot of orange over the white into the center of each mold, avoiding the edges so that you get nice, even stripes.
Follow up with a layer of yellow, and then put the top on the mold.
Add popsicle sticks, and freeze.
