| Abstract: | A smectic A phase was aligned with a uniformly high tilt such that it appeared coloured between crossed polarisers. By applying an electric field the tilt angle of the structure increased progressively giving a Newton Spectrum series of colours. The colours remain on removal of the drive voltage. |
