Ok, the whole thing appears, to us blessed with color vision, as a golden color. And I'm not sure but I think I detect actually 3 different shades/colors. The bottom of the rounded rectangle appears to be a darker shade of gold than the text. More approaching orange but still a gold that's not inconsistent with the text. The top of the rectangle appears to have 2 colors. The top part of it looks just like the text. But then in the place where one would expect a shadow, appears to be a red line (or orange). And I think it's that reddish, orange line that chriswww is talking about.
I actually noticed that too, but remembering you were colorblind, and in the past had said you had help with colors (from friends) assumed that you intended it to be red, possibly as part of a color scheme for clients or something. But I can see where it would be hard to see with certain varieties of colorblindness.
If that red line were black and parially transparent, it really would make a great shadow

(Won't it be great when we finally get objects listed like layers?! Even without colorblindness, I lose things all the time, lol!)
This is off topic, but why can't colorblindness be corrected with colored/tinted lenses? Seems like there would be a way to filter it out.
While we're on the subject, I notice you have a new avatar, but I can't really tell what it is. Black octagon with dark blue bubbles in it maybe, or blue blob with white dots? I'm wondering if it might be a map? But maybe it could benefit by a tweak here and there, too?
