Theres a couple of points to consider in this case Musick...

When it comes to the choice of colours, the general tones are decided upon by textile manufactures. It isn't just one manufacturer that decides, for example, that bright oranges will be popular this year, it's the whole lot of them. It's not coincidence that a whole pile of different brands come out with variations on the same themes. So you don't really have one company at an advantage over an other.

Cosmetic manufacturers follow the fashion industry. All of them have access to the same information, so one manufacturer is not in a better position than another there either.

There is really no monopoly involved since they all belong to the same associations and are aware of the same information.

It's how they interpret and deal with that information that makes them successful or not.
