Line an 8x8-inch baking pan with parchment paper, leaving a bit of overhang on the sides for easy removal.

In a microwave-safe bowl, combine the white chocolate chips and sweetened condensed milk. Microwave in 30-second intervals, stirring between each, until fully melted and smooth.

Divide the mixture evenly between three bowls — about 1 cup each.

Leave one bowl plain (white). Tint one bowl orange and the other yellow, stirring until fully colored.

Pour the yellow fudge into the prepared pan and smooth it into an even layer with a spatula. Place the pan in the fridge for 10 minutes to let the first layer firm slightly.

If the orange fudge has thickened, microwave it for 10–15 seconds and stir until loosened. Pour it gently over the yellow layer and smooth it out. Return to the fridge for another 10 minutes.

Repeat with the white layer, warming it slightly if needed, then spread it evenly on top.

Chill the entire pan for at least 4 hours, or until the fudge is fully set.

Once firm, lift the fudge out using the parchment overhang and slice into small squares.
