<p>Multilayer colour change material, comprising a transparent or translucent top layer, a first colour layer comprising 2 flexible foils, a second colour layer comprising 2 flexible foils, a third colour layer comprising 2 flexible foils, a fourth colour layer comprising 2 flexible foils, a fifth colour layer comprising 2 flexible foils, whereby the first to third colour layer are each connected with a colour fluid reservoir device which allows to influx colour fluid from a colour fluid reservoir into a space between the 2 flexible foils and which allows to drain colour fluid from the space between the 2 flexible foils back into the colour fluid reservoir device, and whereby the fourth colour layer is connected with a black fluid reservoir device which allows to influx a black fluid from the black fluid reservoir into a space between the 2 flexible foils and which allows to drain black fluid from the space between the 2 flexible foils back into the black fluid reservoir device, and whereby the fifth colour layer is connected with a transparent fluid reservoir device which allows to influx a transparent fluid from the transparent fluid reservoir device into a space between the 2 flexible foils and which allows to drain transparent fluid from the space between the 2 flexible foils back into the transparent fluid reservoir device, and a back layer.</p> |
