          Natural light is made up of several different colours associated with

          different  wavelengths  within  the  light  spectrum.  The  colour  we
          associate with anything is the range of light waves that are reflected in
          our eyes by the molecules that comprise the entity. We don’t see the
          colours of light that are absorbed. When it comes to pure water, blue

          light  is  reflected  while  other  colours  of  light,  especially  reds,  are
          absorbed. When looking at the colour of water, it is important to
          note the difference between the apparent colour and the true colour
          of a body of water. The apparent colour is the colour of the water

          when looking at it without removing any suspended and dissolved
          particles. The true colour is the colour of the water after the suspended
          particles have been removed. Suspended particles are things such as
          algae, sediments, or small particles of a mineral. Dissolved particles

          are things such as tannins (a yellowish-brown organic acid that is
