  In 2012, a pedagogic tool for monochromatic holography was realized for
pedagogic and popular science purposes [Th. Voslion and A. Escarguel, Eur. J.
Phys 33, 1803 (2012)]. Following its success, we decided to upgrade it to make
larger colour holograms and new pedagogic experiments. The resulting kit
includes all the necessary equipment to produce 4 "x 5" colour holograms with a
simple optical assembly and with an excellent vibration tolerance. The
resulting holograms, in colour and bigger, are much more spectacular for
science outreach purposes. For teaching purposes, some of the existing
experiments have been upgraded, and new ones have been developed for university
students and continuing education of teachers: colour reflection Denisyuk
holograms, single shot transmission/reflection holograms, angular and
wavelength multiplexing, holographic diffraction gratings with improved setup.
