Personally, I prefer the standard, classic green tunic look for Link. (Or at least the sort of colours of nature that a forest elf would wear... even if Link isn't technically an elf.)
More importantly, I prefer that Link look more quasi-realistic and detailed (as per Twilight Princess) than simple and cartoony (as per Four Swords). That's a personal preference for art styles in general, beyond The Legend of Zelda franchise and even beyond video games.
I liked him the Blue Tunic, with Hover Boots, Mirror Shield, and Master Sword. I felt like a boss, like if I put on *shades* could roll around like I want. That lake? No problem. Got that like a fish, man. IRON BOOTS GO. Though tunic color doesn't really matter as long as I have the hover boots and mirror shield. Love those things.
