set different colors for different link types

[Christian Wittern <cwittern@gmail.com>]

Hi there,

In the archives, I have seen on and off references to a new, extensible
syntax that would go beyond /italic/, *bold* and =code=, but I have seen no
traces of seeing it implemented.

For the time being, therefore I am settling on having different linktypes
coming up in different colors, which I hope is doable, but again, I found no
immediate solution.  I wonder if somebody has an idea of how to go about
this.  What I would like to see is that, for example:

[[file://path/to/my file][myfile]]  comes out visibly different from
[[http://www.example.com/path/to/my file][myfile]] , for example the one in
red, the other in blue.

Any help appreciated,

Chris
