Selecting an area containing similar colors
The Magic Wand tool is useful when you want to select specific colors in
an image. When you click on an image, any colors that fall within the
values specified in the Similarity entry box are included in the selection
area. This is an effective way to select large solid colored portions of an
image, such as a blue screen or patches of skin and clothing.
When you use the Magic Wand tool, it operates in one of two modes, Line
or Area. In Line mode, dragging your mouse over an image creates a line
that calculates the largest and smallest color values of the pixels under the
line (any values entered in the Similarity spin box are also included).
Releasing your mouse then creates the selection based on that range. Area
mode works in much the same way except that instead of taking the
values of pixels under a line it includes all pixels within a selected area.
This mode works best for irregular areas containing similar colors, such
as backgrounds and gradients.
