In a large pot, melt butter.
Once melted, stir in marshmallows, and cook over medium heat, until the marshmallows are melted.
Remove from the heat and stir in rice krispies cereal, mixing until well combined.
Place half of the marshmallow/cereal mixture into a large mixing bowl.
Add yellow gel coloring, and use a cake spatula to fold the color into the mixture. This will take a few minutes to get the color distributed evenly.
Spray your springform pan with non-stick spray.
Spoon the yellow rice krispie treat mixture around the outside edge of your pan.
Use a piece of parchment paper over your and and press the mixture evenly around the edge of the pan, creating about a 1 ½ by 1 inch high border.
Take the remaining mixture and divide it in half again.
To one half of the mixture, add the orange gel coloring. Use the same method to fold the color into the mixture until well distributed.
Spoon the orange mixture around the edge of the yellow, and use the parchment paper and your hand to press the mixture into another circle, about 1 ½ x 1 inch high.
Take the remaining krispie mixture and press it into the middle, filling the rest of the space. If you have too much mixture left you can discard (or eat) any remaining mixture you don’t use.
Allow the mixture to sit in the springform pan for about an hour to set, then remove the outer rim and move it to a cutting board. Use a large knife to cut the mixture into 8 triangles. We cut the whole thing in half, then in half again, then each piece in half again.
Add straws for easy handling, if desired.
