Mix 1 tablespoon melted chocolate with different food coloring to create desired colors. Drizzle colored chocolate into a silicone egg mold. Use a toothpick to swirl colors together to form a marbled pattern.
Pour melted white chocolate over the top and rotate mold to ensure it is fully coated. Allow to cool until hardened, then remove from mold.
Press one half of each egg onto a metal sheet pan that has been heated until the edges begin to melt. Quickly fill with assorted candies, then press the two halves together until sealed.
