I am not an expert on colour-blindness, but would suspect that this 
would not be clear.  If you can, try viewing the page on a monochrome 
monitor, where the different colours would be different shades of grey.

I know I'm out of date and still using WCAG 10, but:


If you are trying to make a visual differentiation, why not style the 
link in a way which makes this more obvious, such as with a background 
image?  A good example of this is that employed by Wikipedia - look at 
the external links at the bottom of articles.

But the biggest issue that springs to mind is what happens in a 
non-visual context?  How are you going to convey this information to 
screen reader users, for instance?  Just something else to consider.
