Water Sort Puzzle

Tap on a glass to choose it, then click on another glass to move the water. Only pour water if the surface color of the first glass matches the surface color of the target glass or if the target glass is vacant. Sort the colored water so that each glass contains only a single color. Solve all the glasses to advance to the next level. Employ planning to prevent getting stuck with unmovable colors. Note that some levels may require multiple moves to solve.
