Komatsu Matere has been developing materials that contribute to the preservation of the environment. One of their goals was to find how to dye synthetic fibres with natural materials. As a result of testing various vegetables, the company found that the pigment from onion skin can efficiently dye synthetic fibres. Colours are created by combining onion skins with olive leaves, squeezed olives, wine, squeezed grapes, rice husks, bamboo charcoal, etc.
Onibegie® can produce colours and textures unique to plants. For example, even the natural pigment in the colour beige comprises of dozens of colours, and that is why this colour has such a subtle depth. Another of its charms is that the longer it ages, the more flavourful the colour becomes.
