Just when you think you know all there is about a famous and long-running character like Luigi, Nintendo's Shigeru Miyamoto goes and throws us all a curveball. Speaking with MTV Multiplayer about the company's Year Of Luigi initiative for 2013, the character's creator revealed that those green overalls are no coincidence. Like every other design choice of the era, Luigi's colors are the way they are for an important system resources reason. While Mario's design and colors are based on the hardware limitations of the day, so too is Luigi bound by the hardware from which he spawned. For instance, he takes his colors from Mario Bros. shellcreeper turtle precursor to the Koopa Troopa.
Multiplayer: Do you think that the red and green colors, the two that were chosen for Mario and Luigi, are important, or were they just products of the technological limitations at the time?
Miyamoto: I think that the red and green choices were the right ones to make, especially where "Mario Bros." is a two-player game, and you needed to be able to tell which one you were controlling. But, in fact, as you note, the system at the time had severe limitations as to the number of different colors that could be used in the palette. What we ended up having to do was look at the green of the turtle characters in that game, the shells were green, and the color of their faces was essentially somewhat skin tone, so we were able to use the same color palette as the turtle on the Luigi character. So, because of the limitations, we had to make that decision, but looking back on it now, it appears to have been the right decision to make.
Of course, as those limitations have gone away, and we've had more colors to use, Luigi is not only green, but he also has his own blue shirt. In "Mario Bros.," he originally had a white shirt, but now he has a blue shirt, and we were able to make him a little bit taller and things like that to differentiate him.
It's always fascinating to see how our favorites characters not only began, but have grown and changed over the years. So many of video gaming's most iconic characters have their designs rooted in practical needs to overcome problems. I wonder what Mario and Luigi would look like if they were created today in a time when character design is much more open and free compared to thirty years ago. Would they be realistic in style? Would their wear different clothes? Would they even have their trademark initial-marked hats? All things considered, I think we're better off with the way things turned out. I don't want to live in a world where everyone's favorite plumbers look like, say, Uncharted's Nathan Drake and Victor Sullivan. It may be serendipity that Luigi looks as he does, but his design suits him well.
