With the colour change materials that react to heat stimulus – thermochromics – the possibilities of mixture solutions with conventional pigments emphasizes a re-thinking of colour as dynamic design material. In this work, smart materials are applied in order to achieve textiles that can change from one initial colour to others, namely, those that have been combined to create them. The aim is to transform the light that goes through them, designing dynamic ambience light, without acting upon the light source. Thermochromics and conventional pigments have been combined through different colours and measured in intensity and colour of the light parameters. The smart materials applied to textile fabrics changes the light transmitted, once the pigments require light to be absorbed to obtain colour. The results reveal that thermochromics and conventional pigments can be combined and applied in textile filters, providing the ability to transform the monochromatic light to colour, in order to create dynamic ambience light.
