Well obviously the hud in the first picture is not 100% opaque. Otherwise I wouldn't be able to see through it, would I? Just take another look. Opacity is the opposite of transparency AFAIK.

If the first picture were 100% opaque, it would be 100% solid, and thus 0% transparent. It is obviously partially transparent, and thus somewhat less than 100% opaque.
