Begin by lining three large baking sheets with parchment paper and setting them aside.

In a large pot, heat a few tablespoons of coconut oil over medium heat until shimmering. Drop in a couple of popcorn kernels to test if it's hot enough; once they pop, add the remaining kernels. Cover the pot and shake occasionally. When the popping slows to every few seconds, remove from heat and sprinkle with popcorn salt before dividing into three bowls.

Grab three separate microwave-safe bowls and add an equal amount of white chocolate chips to each. Combine each with a teaspoon of coconut oil. Microwave each bowl in 30-second intervals, stirring in between, until all chocolate is melted and glossy.

Add a few drops of food coloring to each bowl, creating vibrant hues of orange, green, and purple. Stir thoroughly to combine.

Pour the colored chocolate over one bowl of popcorn, gently tossing to coat. Spread on one lined baking sheet to set.

While chocolate is still warm, sprinkle desired mix-ins over the coated popcorn and gently incorporate.

Allow the popcorn to set for about 5 minutes, maintaining a festive look.

Once set, break into clusters and transfer your colorful Halloween Popcorn into festive cauldrons or goodie bags for serving.
