Under "Get this Coin" what do different colors of names mean?

At the bottom of the page for each coin there is a section called “Get this coin”

There is a list of names of people who have the coin available for trade.  What do the different colors of their names mean?

The faded ones haven't logged in in quite some time as far as I remember.

The faded ones haven't logged in in quite some time as far as I remember.

Or have marked on their profile that they "don't want to swap for the moment”

There are three different colors.  How do you know which one means what?

From How can I find a swap partner? :

This section shows the names of the users who offer that coin or banknote for swap (if any). You can click on a name to go to their swap list and initiate a swap. Pick preferably the users displayed in a darker blue: they are the more active users of Numista and you will have a higher chance to get a positive response.

I don't think there's a third color unless it's the browser's way of saying you've already clicked on that link.

Edit: I just clicked on those two and the color changed from the darker blue to the purple.
