From my friend in Japan, here is the translation of 'Nishiki':

Original meaning is from silk textile, fabrics that have ma...Read Moreny colors. They are made by colorful yarn, red, gold, silver yarns, are very beautiful, thick fabrics and beautiful pattern, very expensive. These are used for Japanese Kimono.

Original meaning is based fabrics, but we usually use Nishiki for Beautiful, Gorgeous and for fine things.

We use Nishiki for a person who was with great success. We say a person who brought Nishiki to his or her home country. It means he or she achieved their success greatly, and became very rich, and came back to their home country with nice rich clothes. It means fine succeeded person.

And sometimes we use Nishiki for beauty of turned color leaves that are red, yellow, gold, orange mixture beautiful colors in autumn. We say "Nishiki of momiji". Momiji is Japanese maple trees. It is many beautiful colors that were originally from a beauty of Japanese Kimono fabrics.
Nishiki means fine things like these.
