The Select by Color tool is designed to select areas of an image based on color similarity. It works a lot like the Fuzzy Select tool. The main difference between them is that the Fuzzy Select tool selects contiguous regions, with all parts connected to the starting point by paths containing no large gaps; while the Select by Color tool selects all pixels that are sufficiently similar in color to the pixel you click on, regardless of where they are located.
