Whisk the pudding mix and cold milk together in a large bowl for two minutes until smooth and thickened.

Divide the pudding into three separate bowls. Add the yellow food coloring to the first bowl and stir until the color is even. Add the orange food coloring to the second bowl and stir until uniform. Leave the third bowl plain.

Spoon the yellow pudding into the bottom of four clear glasses, using about one-third of the mixture in each glass.

Add the orange pudding on top of the yellow layer in each glass, again using about one-third of the mixture.

Top each glass with the plain pudding layer, then finish with a dollop of whipped cream and three candy corn pieces per glass.
