Essentially what Line and many other ski manufacturers do is called "die cut bases". They use certain colors like for instance, last years chronic' bases; mine are white with black and orange lettering. They do that so they don't waste as many materials and money. It may seem odd but they will use the black bases, lay in the white lettering, and use the excess black base material to put the black lettering on the bases of white-bottomed skis.
