2. Then select the option in the menu bar, and select the color range option in the pop-up drop-down list, as shown in the figure.
3. Then the color range setting window pops up, and the top option is sampling color. After clicking, you can see many color options. You can choose the one you need.
Then we choose a red color to test it. After clicking the red color, the red area will be displayed in the preview below. Of course, areas that are not red cannot be displayed. This is only used when the red area is selected.
Next, let's choose a green color to see the effect. Why do we choose green? Of course, the monitor is not on the screen, just to compare the effect. After choosing green, we found that the preview window was dark and there was nothing to choose. That's right, that is to say, without green, the choice of green range will not succeed.
6. Of course, there is no color we need in the list. It doesn't matter. We can customize the sampling color, select the sampling color option, and then select the pipette icon on the right. 1 is a financing tool, followed by a ups and downs tool.
7. Next, use the eyedropper tool to select the background color except squirrel, click in the picture and click in the preview window, and you can see that the selected area in the preview window is displayed as white, and the unselected area is black.
8. There is also a color tolerance option at the top of the preview window. Adjust the color tolerance to adjust the range of the selected color. The smaller the value, the smaller the range, and the larger the value, the larger the range. As shown in the figure, a large value is set and some squirrels are selected.
9. Adjust the appropriate color tolerance, and then click OK. In the ps interface, you can see that there is a choice on the picture, that is, the background is selected.
