I disagree. We reply on context and content to indicate interactivity. Color has been a pseudo indicator and is now inaccurate at best and misleading at worst. Just take a look at the header of this comment; the username timestamp and link are all the same color, yet only two of the three are actually links or clickable at all. Thus, the content and the context indicate clickability, not color. This is why UI design is harder than everyone thinks.
