Improve the visibility for hyperlink

This normal text.

This is normal text with an hyperlink.

It appear that some people can fail to see the hyperlinks. They are of soft purple, very soothing and subtle and pretty. That said, I am not sure that people with different screen configuration can see them, not to speak of eventual sight problems or colorblindness.

The need for an automated underline the the link would fit with regular uses and signals to say "hey, hyperlink here". I would suggest an other color,  why not the same color, more "agressive" for it to be more distinct. If all else fail, the seering royal blue of usual hyperlinks would be a safe bet, I suppose.
