font-lock-comment-face to a Strong Color

Question

If I describe-face over a strong color in Emacs, it tells me that its foreground is #ffd700, but when I eval this:

(set-face-attribute 'font-lock-comment-face nil :foreground "#ffd700") 

..it has a grayed out yellow color;)

See screenshot here:

1. The color I want
2. The color I get

Is there some secondary color here or something?;)

C-u C-x = gives me:
