Bring the coconut milk, water, salt, and sugar to a boil in a heavy saucepan. While boiling, whisk in the tapioca and continue to simmer until tender, 12 to 14 minutes, stirring occasionally. Cool immediately by placing in a flat bowl and covering the surface with plastic. Let rest about 2 hours. When cool, add the lemon juice. Stir to incorporate. To make green, add drops of food coloring to desired color.
To serve, scoop into individual bowls.
