In a large bowl, whisk together heavy cream, milk, sugar, and salt until combined.
Stir in Skittles candies in the color of your choice. I use all red, pink, and purple for a pretty pink ice cream.
Cover bowl and let mixture chill in fridge for at least 4 hours, stirring on occasion.
Strain Skittles candies out of mixture (they should be mostly white) and pour strained milk mixture into ice cream maker. Process according to manufacturer's directions, likely running for about 20 minutes.
Transfer ice cream to containers and freeze for at least 4 hours before serving.
