Select by colour works really similar to the Fuzzy Selection tool. The main difference is that when magic wand makes selection with no real gaps, selection by colour takes all the pixels with similar colour, regardless to where they are located.
Modes - determines the way of creating the selection, whether it'll be combined with existing one and such
Antialiasing - causes the boundary of the selection to be drawn smoother
Feather edge - causes the boundary of the selection to be blurred
Select transparent areas - gives the ability to select areas completely transparent
Sample merged - creates a selection from actual image, instead from the active layer
Threshold - determines the range of colours
Select by - select, which component shall be used for calculating the similarity
Modes, Antialiasing and Feather Edges
