We are curious whether the colour of Flaska means that it is informed differently, as in the case of glasses, or is that merely a design? If it is just about the design, are then all of Flaskas informed the same way?

All the bottles are programmed the same way. General programme for good quality water is inscribed into Flaska. The colour of the protective sock does not have anything to do with the information and merely serves as a design – people and their tastes differ and accordingly, different colours please them.
