Colour - The Spectrum of Science
|
We
take
colour
for
granted.
We
have
to,
because
otherwise
we’d
be
entirely
distracted
by
it.
But
once
in a
while
it’s
rewarding
to
pause
and
look
a
bit
closer,
just
to
see
what
those
colours
are
telling
us.
And
then
we
can
go
back
to
taking
it
for
granted,
but
our
world
is
richer
because
now
we
know
the
stories
hidden
in
the
code.The
colours
that
we
see
are
only
a
fraction
of
what's
out
there.
Beyond
the
rainbow
there
are
colours
invisible
to
our
eyes.The
colours
we
see
are
far
more
complex
and
fascinating
than
they
appear.
In
this
series,
Dr
Helen
Czerski
uncovers
what
colour
is,
how
it
works,
and
how
it
has
written
the
story
of
our
planet.
This
series
explains
how
each
of
these
colours
occurs,
unlocking
the
mysteries
of
nature
and
the
forces
that
underpin
the
Universe
itself.
More
than
any
other
planet,
the
Earth
is
awash
with
colour.
With
its
flowers,
oceans,
rainbows
and
vast
array
of
animal
life,
our
planet
stands
out
from
the
blackness
of
space
as a
multi-coloured
jewel.
Our
eyes
allow
us
to
experience
colour
as
an
explosion
of
vibrant
wonder.
In
Search
of
Colour
examines
the
science
behind
this
miracle
of
nature,
and
travels
across
the
world
to
discover
what
makes
our
planet’s
palette
unique.To
investigate
the
essence
of
sunlight
Helen
travels
to
California
to
visit
the
largest
solar
telescope
in
the
world.
Helen
discovers
how
the
most
vivid
blue
( Lapis
Lazuli
) is
formed
from
sulfur
atoms
deep
within
the
Earth’s
crust
and
why
the
presence
of
red
ochre
is a
key
sign
of
life.
In
gold,
she
discovers
why
this
most
precious
of
metals
shouldn’t
even
exist
on
the
surface
of
the
planet.
The
raw,
early
Earth
had
plenty
of
colour,
but
that
was
nothing
compared
with
what
was
going
to
come
next.
That
canvas
was
about
to
be
painted
with
a
vast
new
palette
-
and
the
source
of
those
colours
was
life.
Green
is
the
colour
of
the
natural
world
and
yet
it's
the
one
colour
that
plants
have
evolved
not
to
use.
Dr
Czerski
explores
colour
subjectivity
by
trying
on a
dress
that
recently
divided
the
internet
—
to
some
it
appeared
blue
and
black,
to
others
white
and
gold.
It's
a
perfect
fit.
It's
also
a
neat
analogy
of
how
people
can
have
opposing
views
but
both
swear
blind
that
their
perspective
is
correct.The
series
ends
with
some
amazing
imaging
techniques
that
show
our
bodies
in a
whole
new
light.
We
can't
see
in
ultra
violet,
but
many
animals
can.
With
the
discovery
of
x-rays
we
could
look
inside
ourselves
in
ways
that
previously
had
only
been
possible
after
death.
Today
those
same
x-rays
allow
us
to
examine
life
at
the
atomic
level,
helping
to
develop
new
drugs
and
better
materials.
...Ultimately,
by
harnessing
all
the
colours
there
are,
researchers
are
beginning
to
image
the
human
body
as
never
before,
revealing
new
ways
to
treat
disease.
