Spektraflux
Spectroflux is an optically active liquid that changes its colour structure depending on light conditions and movement. At rest, it produces a black and white marble pattern, while when moving it switches between shades of the rainbow spectrum. This effect is due to changes in refractive index and particle orientation that affect the path of light. Mechanical motion changes the orientation of the particles and thus their refractive properties, leading to changes in colour perception. The high viscosity of the liquid stabilizes the optical patterns and allows a smooth transition between colours during movement.
