I asked around on a bunch of questions websites for professional nerds
to read and attempt to answer; as well as some nerdy friends of mine. :)
and
here's where I am now:
Reflection: When a wave meets a boundary, it can be
reflected or transmitted. Reflection can be partial or complete. Reflection can
also involve a phase flip (change of phase of 180 degrees.)
Refraction: Occurs
when a wave crosses a boundary from one medium to another. A wave entering a
medium at an angle will change direction.
Diffraction: Refers to the "bending of
waves around an edge" of an object. Diffraction depends on the size of the
object relative to the wavelength of the wave.
which brings me to my question: are water and milk technicaly the same
colour?
in short no. sad right? let me explain like in BBC Bitesize amounts.
Water is technicaly colourless because it has total reflection going on
compared to milk. partly because water and milk have different densities.
(for a few reasons including how milk is made) but mainly because when light hits water, most is REFRACTED and DIFFRACTED and some is REFLECTED.

with milk,
less light is diffracted and more light gets absorbed.
so in conclusion, translucent objects are different coloured to opaque objects.
