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 Merge option lets you grab the color as it is in the image, resulting of the combination of all layers. Only colors in visible layers are used. An Info window opens when you click on the image.
