3D Colour
3D colour is the exact opposite of 2D colour.
It can be felt and some instances smelt.
During the first stone-age period, historical
findings of wall paintings in caves have proven that the only two colours that
were dominant were black and red. The second stone-age period witnessed the use
of bold black, red and brown. The people of this era begun mixing colours, also
the came out with some colours such as amber red.

During the BC era some of the oldest rock
pigments were discovered an example being the mountain green colour which is
derived from copper ore and is in rock form. It has been used in some paintings
and is not affected by light hence it remains the same as it is on earth

Colour is not derived from rock pigments. In
the period of the Classical Times, colour
was derived from mainly petals of bright flowers such as hibiscus as well as
their roots, so if for instance you want to get a reddish colour you would have
to find a red bright flower or plant roots that you could derive these colours
from derived from.

Today colour is derived from various metals
with very different chemical compounds, examples of such colours are Molybdate Orange, Manganese Blue and
Cadmium Yellow Lithopone.

sources for pigments ( ground )
The focus of this report however is going to be
on how colour is derived from rock pigments.
These kind of rocks are derived by the sediments from construction sites.
The colours obtained from these sources are often not too bright, they could
either be very dark, dull or fairly bright.
