When I enter the "Select Color" dialog box, the surrounding colors will darken. This seems very normal. But,When I pick up colors from the screen, it will pick up the color of the darkened screen instead of the original color of the screen.
As shown in the picture, when I pick up the white on the screen, it actually picks up the darker gray.
