Will the colour stay?
The slight variations caused partly by the artisanal production methods, in our view, add beauty and make the fabrics seem alive. That said, many of The Colours of Nature dyers have been with the company for 20 years, some more, and they generally achieve great results also where uniformity is required. We are proud to say that with persistent research and development we have achieved fastness equal to that of synthetic dyes (level 4‐5 for wash and light fastness for all hues, including Turkey red, which is notoriously difficult.
Washing in water containing iron can sadden the shade and it is best to keep items away from contact with bare iron metal.
Soaking in or washing with alkaline hard water, soap, cheap bar detergent or strong powder detergent may result in a change of shade and acidic spillages will cause discolouration.
Soaking in bleaching solutions or washing with detergents containing bleach may lighten the shade as can prolonged exposure to chlorinated swimming pool water.
Direct sunlight can negatively affect colour fastness, which is why we suggest drying naturally dyed fabrics and garments in the shade.
Long term exposure to atmosphere with oxidising gases such as ozone and nitrogen oxides may fade colour, especially at the folding line. This is more distinct in light indigo garments than darker ones and for garments stored at boutiques, in direct contact with air rather than in a drawer or wardrobe, we therefore keep them in ziploc bags, not only to protect them for dust.
