Dissertation -Departamento de Artes & Design, Pontifícia Universidade Católica do Rio de Janeiro.The indigo is a blue dye from vegetal origin with records of its use that turns back in to the first civilizations. It's tradition as a dye plant comes from the great quality of dyeing it offers for both animal and vegetal fibers. Besides that, the indigo plant leafs has the peculiarity of providing also the color blue as insoluble pigment, and so, it increases its using possibilities. The present research has as a go, to explore possible applications of the natural indigo pigment in artistic materials as way of extending the range of available products with this raw material.Experiments have been conducted in order to test behavior, resistance towards light, and the pigment applicability over four different dyeing techniques. The performance of the developed materials were enough to support the use of the natural version of the indigo pigment as an alternative to the synthetic, presenting yet the advantage of being less toxic and pollutant. Its expected that the increase of application variety of the natural indigo will stimulate, by consequence, the interest for the development of new products, and also, for its story, favoring the rescue of the traditional knowledge and practices of the indigo plant cultivation in Brazilian localities with a history cultivation in the past.
