Figure 13.18. Select by Color tool icon in the Toolbox
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 (“Magic Wand”). The main difference between them is
that the Magic Wand 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.
2.6.1. Activating the tool
You can access to the Select by Color Tool in different ways:
2.6.2. Key modifiers (Defaults)
The select by color tool does not have any special key modifiers,
only the ones that affect all selection tools in the same way.
See Selection Tools for
help with these.
Using Select by Color tool: selected pixels are not only contiguous
As with fuzzy tool, the selection starts as soon as you click and the
reference is the first clicked pixel. If you click and drag, you can
change the threshold by the same way as with the fuzzy tool.
To move the selection see
Figure 13.20. Tool Options for the Select by Color tool
Normally, tool options are displayed in a window attached under the
Toolbox as soon as you activate a tool. If they are not, you can access
them from the image menu bar through
→ → which opens the option window of the selected tool.
See Selection Tools
for help with options that are common to all these tools. Only
options that are specific to this tool are explained here.

All these options work exactly the same way, they were described
for the fuzzy selection already. See for
