Did you mean shiney?? Well, I did shiney patent leather shoes by painting black food coloring on top of fondant. It came out very shiney!
You can use confectioner's glaze to make it shiney. 
You can use steam too. I seen it on Food network one time during a cake challenge and I also seen it done during a demo at my guild club meeting. I haven't tried it yet, but I plan to.
I use my wilton icing colors mixed with vodka, and painted on. I have a penguin and a killer whale in my pictures that were both done this way. Both are pretty shiny!
Confectioner's glaze is something you can buy. I'm sure you can make it too, though I haven't done it myself. You can buy it in a spray can like this:

or in a bottle like this:

Nope, they dried just fine! I also painted the tires on the little ATV cake that way... No problems with stickiness, since the alcohol evaporates quickly! 
Also, I should point out that all my painting was done on WHITE fondant, so you probably wouldn't need as much color as I did, if you're painting on top of fondant that's already black... Good luck!
I think that black fondant looks really shiney if you put it on a piece of plastic wrap (I don't know what you call it, ceran wrap mabye?) and roll it out without any corn flour. I just use a non-stick rolling pin and roll it out on the plastic, then lift the whole thing up, turn it over in my hand or on my arm depending on the size, peel of the plastic on the back and then place it on the cake. The bottom side that was against the plastic needs to be the side attached to the cake because it will have wrinkles from the plastic.
I did just like this with the black fondant on a pirate cake just a week ago. The cake was assembled the day before, and the picure taken the day after. As you (mabye) can see from the picture, the black is still shiney and has not dried up at all.

I just used the regular gel color mixed with a tiny bit of vodka to paint it and it came out very shiney. It was super easy!
