I personally don't see a problem with the current labels. (I'm just a
random passerby here.)

I think here you have a point.

According to the "Web Content Accessibility Guidelines"[1], if I
understand them correctly, then if you use only color to distinguish
links, you need a contrast ratio[2] of at least 3:1 with surrounding
text. lua.org's contrast ratio is 1.3:1 (where normal text is #000000
and links #000080). But you're allowed(?) to work around this by
providing another visual cue, like an underline. Indeed, when I visit
w3c.org's frontpage I see that while their contrast is only 1.67:1,
they do use a nice underline.

Here's a CSS I suggest for lua.org's:

    /* Show a dainty underline only for links inside paragraphs
     * (not for ones in menus & headers!) */
    p a { border-bottom: 1px solid #A8BFCF; }
