Take equal parts yogurt and fresh diced mango, and puree. Add honey to taste and a few cubes of ice (~2 per cup of yogurt), and blend until ice is mixed up and the mixture is a bit fluffy.
Pour 4/5 of the mixture into a separate container, add green food coloring to the remaining 1/5, blend until green.
Pour the green-color mango lassi into the bottoms of the cups. Pour half of the plain (yellow) mango lassi over the back of a spoon into the cups. Some will add to the height of the green, so it should end up roughly equal.
