Other than the Kokiri tunic, I like the Goron Tunic on Link a lot because the red goes nice with his golden hair. The Zora tunic doesn't have the same feeling but I still like it. I actually once had a large blue shirt of my dad's and I made it into a Zora tunic. That was so awesome.
I stick to Red, the Goron Tunic. I really love the color green and Link's standard color is the green tunic, but the red tunic was a epic combination with the golden Gauntlets and the Mirror Shield. I always loved to use the Red tunic, in Brawl the Red Link is also my favorite. But in Ocarina of Time it was just the coolness of the combination tunic, normal boots, shield and gauntlets.
Unfortunately i didn't see the red tunic ever again, except the stupid armor in TP.
The Goron tunic, its totally awesome and it always looks cool on him all the time. Also on youtube there is this video called The Lost Tunics where this guy hacked his N64 and when he selected a tunic three times the tunic would look lighter or darker in color. And there were also a black,white, and purple tunics as well.
