color, typically a shade of red. It must be used scarcely."

regular/bold). IT is generally used for titles, keywords,
directory, etc."

the face uses a different hue with approximately the same
intensity as the default face. This is typically used for links."

It is made by using the same hue as the default but with a lesser

secondary information and also replace italic (which is generally
abused anyway)."
