Sustainably blue

Art & Leisure

Did you know that most people can distinguish between approximately 200 different colours?

Jeans are usually blue, and now, thanks to a research team based at the University of Georgia, their colour comes about in a natural, environmentally-friendly way.

The team mixes indigo particles with cellulose fibres and a natural sugar which can be harvested from seafood waste. The result is a dye solution.

The natural sugar ensures that the hydrogel adheres to the denim and can’t be washed out. Colour intensity can be modified by adding more or less indigo.

The process is free of chemicals and saves water and time. The textile industry, it seems, is starting to be quietly revolutionised.

A blueprint for the future.
