I've only seen four so far.

The first one is khaki, a high-end style made in Europe and America.

The second kind is red, which belongs to Hong Kong and Asian products. There are few low-end casual styles.

The third is the Japanese black label, which is specifically aimed at Japanese men and white-collar workers.

The fourth is the blue label of Japan, which is exclusive to women's leisure in Japan.

I haven't bought anything from persson, and persson should also be the exclusive color.
