How you attain your rainbow of ice cream hues is up to you: you can either use ice cream flavors which are naturally tinted in the colors of the rainbow (strawberry for red; orange flavored for orange; French vanilla or banana for yellow; green tea or mint chocolate chip for green; any kid-friendly blue ice cream for blue; blueberry for violet; et cetera), or if you don't want to invest in five ice cream flavors or feel that the flavors might not be harmonious, you can also attain this look by tinting vanilla ice cream with food coloring.
Simply stack your colors in popsicle molds (I used the Orka mold) or even paper cups, insert a stick, and let them freeze. This recipe couldn't be easier, and the finished product is a pleasurable frozen treat with a visual twist which makes it that much more delightful to eat.
For best results, use ice cream that has been softened to the point where it is almost, but not quite, liquid.
