5.4. Color Picker

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. Activating the Tool

There are different possibilities to activate the tool:

  • From the main menu: ToolsColor 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. Key modifiers


Ctrl does nothing here. But, when using a paint tool, pressing Ctrl allows you to pick colors without having to switch to Color Picker tool.


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.

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