Indigo blue is a pigment historically extracted from plants and was mainly used for the production of denim cloth for blue jeans. Nearly all indigo produced today is synthetic.
"I have often said that I wish I had invented blue jeans: the most spectacular, the most practical, the most relaxed and nonchalant. They have expression, modesty, sex appeal, simplicity - all I hope for in my clothes." – Yves Saint-Laurent
Denim blues mixed with fluorescent yellow and grey has a great contemporary edge and I love the combination. colourlovers
