### 2.7. Seleccionar por color

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.

#### 2.7.1. Activar la herramienta

Hay varias maneras de activar la herramienta:

- From the main menu: Tools → Selection Tools → By Color Select.

- By clicking the tool icon in the Toolbox.

- By pressing the Shift+O keyboard shortcut.

#### 2.7.3. Manipulación de la herramienta

Figura 14.23. Usar la herramienta de selección por color: los píxeles seleccionados no son sólo contiguos

As with the Fuzzy Select 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 Select tool.

Puede mover el contorno de selección con las flechas del teclado, no con el ratón.
