I'd call them ice pops. Favorite would be purple/black assuming they're "grape^tm^", because I'm a trash person. Second would be red, third would be orange. Blue would weird me out so I wouldn't try it. It's probably raspberry, which I'm not a fan of. Finally, I'd assume green was sour apple or lime, which I also don't like. Though if they turned out to be watermelon then I'd be missing out
