### 5.4. Recoge-color

The Color Picker Tool is used to select a color on any image opened on your screen. By clicking a point on an image, you can change the active color to that which is located under the pointer. By default, the tool works on the active layer, but the Sample merged option lets you grab the color as a composite from all visible layers. Only colors in visible layers are used. A Color Picker Information window opens when you click on the image.

#### 5.4.1. Activar la herramienta

There are different possibilities to activate the tool:

- From the main menu: Tools → Color Picker..

- By clicking the tool icon in the Toolbox.

- By pressing the O keyboard shortcut.

- By pressing the Ctrl key while using a paint tool. The Color-picker dialog is not opened during this operation and the tool remains unchanged after releasing the key. Nevertheless, you can get information by using the Pointer window.

#### 5.4.2. Teclas modificadoras

Ctrl

  Ctrl no hace nada en este caso. Pero, cuando se utiliza una herramienta de pintura, al pulsar Ctrl le permite recoger colores sin tener que cambiar a la herramienta Recoge color.

Shift

  If the Use info window (Shift) option is not checked, pressing the Shift key when you click on a pixel opens the Color Picker Information window.

  | Nota
  The Pointer Information gives you the same information permanently. Note that it defaults to Sample merged.

#### 5.4.3. Opciones

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 main menu through Windows → Dockable Windows → Tool Options which opens the option window of the selected tool. The available tool options can also be accessed by double clicking the corresponding tool icon in the Toolbox.
