In the first image the cursor isn't hovering above any of the buttons. In the second image the cursor is above the square. As you can see, the square is now somewhat darker compared to when the cursor wasn't hovering the button. In the third image the cursor is above the down arrow. Because the cursor is hovering this arrow, the arrow now looks more dark and the square looks grey again. But also look at the close button. Both the minimize button and the close button have a darker color than the first button. The square is grey, while both other buttons have the dark color. If you'd show me the third image and ask me the question: "Above which button is the cursor hovering?" I'd answer: "Above the square, because that button looks somewhat greyed out and the other two don't." In the fourth image the mouse is hovering above the close button. As you can see, the X now has a grey color, while in the above three images the X had the dark color. This button looks greyed out when the mouse is hovering it. This is exactly the opposite as the behavior of the other two buttons. The square and the down arrow are grey when the mouse isn't hovering the buttons, while the X has a dark color. When you place your cursor above the square or the down arrow their color change from grey to black, while the color of the X changes from black to grey. In the fourth image the square, the down arrow and the X appear to have the same color. It doesn't look like the cursor is hovering one of these butons, although is mouse pointer is above the X.
