>> As a lighting designer, my job is
focused on transformation.
I take blank slates, empty theaters,
stages, sets, costumes, and turn them
into nuanced, cohesive visual worlds for
performers and audiences to inhabit.
Lighting designers are uh curators in
that we generally don't work in
isolation.
Instead, we take content that's mostly
designed by others, like sets and
costumes and on-stage action, and we use
tools like color,
texture, and intensity to shape an
audience's perception of the work of
those directors and other designers.
My job has a couple of parts. By day, I
run the MFA program in lighting design
at the University of Georgia, where I
teach graduate and undergraduate courses
in lighting design and technology, and
maybe most importantly, where I mentor
student designers preparing for careers
in the entertainment industry.
By night, I work professionally as a
lighting designer, where I collaborate
with theater, dance, and opera companies
in addition to orchestras across the
country.
As the designer, it's my job to decide
which lights we'll use for a production,
where we'll put them, how they'll get
focused, and to manage all the people
involved in that process.
Once everything's working, we use a
computer to store a set of light cues,
which are sort of like photographs in
that they represent discrete instances
of different combinations of lights
doing different jobs.
I often find that the strongest
reactions to my work come from dramatic
shifts in color.
Most of my personal practice is in the
theater, where it's common to move
quickly from relatively realistic scenes
lit mostly in white to big, dramatic,
colorful looks. And those transitions
often yield strong audience reactions.
Because they're rich and visually
dynamic, yes, but also because we're
biologically and culturally attuned to
color and its meanings.
Understanding those associations allows
me to deploy color strategically in my
work to emphasize meaning, direct
attention, foreshadow, and set a mood on
stage.
Our experience of the world around us,
including color, starts with
photoreceptors, which are cells in the
retina that collect specific kinds of
light and pass it off to the brain for
processing.
Rods help us sense light and dark,
motion, aid in peripheral vision, and
can function even in low-light
conditions.
Cones function best in brighter light
and respond specifically to red, green,
and blue wavelengths, which in
combination allows us to give see a full
range of colors.
But vision alone isn't enough. We really
need our brains to name and
contextualize color information if it's
going to be of any use to us. Without a
word like red, for example, we wouldn't
have a way to warn others to avoid
poisonous red berries.
Experts generally agree that languages
develop color words only as they're
needed. So, while we've had the same
photoreceptors and been able to see the
same colors as long as we've been a
species, our color vocabulary has
shifted dramatically over time.
One famous example is Homer, the Greek
poet, who often referred to the sea as
wine dark because the ancient Greeks
didn't have a word for blue in the same
way that we do.
It does appear that all languages have
words for black and white. An ability to
describe that distinction is probably a
biological imperative because it allows
us to do things like identify the
difference between good and bad weather,
talk about movement, maybe even point
out the location of a camouflaged
predator.
Incredibly, after black and white, every
language has developed color words in
exactly the same order.
So, next comes red, which is likely
useful for identifying danger.
Then yellow and green, which probably
help us talk about food items.
Then blue and brown.
And finally, purple, gray, and pink.
The colors at the end of that list are
really biological wants rather than
needs. Highly industrialized societies
might benefit from words like purple and
pink to help us describe manufactured
items in daily use.
Less industrialized societies, of
course, can see all the same colors, but
might have less need to describe them
with a single word.
Once we have a variety of words to
describe things, it's natural for us to
start sorting those words by their
characteristics, and color is no
exception.
All colors have at least two definable
qualities, which we call hue and
saturation.
Hue is just another word for color. So,
red, orange, orchid, tan, and green are
all hues.
Saturation describes depth of color. Sky
blue, for example, describes a blue
that's probably closer to white than
navy blue. And forest green describes a
green that's almost certainly deeper or
darker than grass green.
Combinations of hue and saturation evoke
predictable and often universal
responses.
Red makes us feel angry or passionate,
and bright red can make us feel like the
thing we're looking at is urgent.
Biologically, that's because we're
primed to detect blood flow to the skin.
Both because that's a way to know
whether other people are interested in
us, like when they blush, and also to
detect anger and prepare for possible
fight or flight.
Red also has strong cultural
associations. We often use red signs,
for example, to mean stop, go here in
case of an emergency, or danger.
By contrast, blue makes us feel calm or
peaceful.
Exposure to blue in general and blue
light in particular seems to stimulate
the production of serotonin.
Culturally, that might be because we
associate blue with the open sea or sky
and a lack of captivity.
One of the most astonishing aspects of
visual processing is that our brains can
see colors our eyes can't. There's no
pink light, for example, on the visible
spectrum. Visible light waves go from
red to purple through green, but we
experience color in a circle rather than
on a straight line, and our brains have
invented pink to fill in that empty
space.
Pink is a relatively new addition to the
English language. It was first written
down during the Renaissance, and it's
one of our more controversial color
words because of its associations with
femininity.
But that pairing is also fairly new.
As late as the early part of the 20th
century, contemporary color gender roles
were reversed.
Blue was associated with femininity
because it was felt to be delicate,
while pink was strong and masculine.
Those roles reversed in the 1940s and
'50s, which is probably a strong
indication that there's no concrete link
between color and gender or sexuality.
While some of our color associations
have strong physiological components,
others are strictly cultural. And we
often need that cultural context to help
us inform color meanings because lots of
colors have contrary victory
connotations.
Green, for example, seems to evoke a
generally peaceful physiological
response, but it has much less pleasant
cultural connotations like greed and
jealousy, reptiles and amphibians, or
illness.
Similarly, some color associations are
universal, but others are definitely
local.
Yellow is closely associated with
lightheartedness or happiness in in
United States, but in ancient Egypt or
contemporary Myanmar, yellow is a
morning color.
In China, red is closely associated with
good fortune and prosperity, but in the
United States, much more so with anger
or passion.
Advertisers routinely play on our
biological and cultural associations
with color.
What sort of businesses do you think of
when you look at this color combination?
Maybe you said things like health
insurance or agriculture. And that makes
sense given the generally peaceful
associations we've already identified
with blue and feelings of calm, health,
and trustworthiness that can accompany
green and white.
How about this combination?
Good participation.
You almost certainly said things like
fast food or maybe gas stations. We've
already seen that exposure to red can
prepare the body for fight or flight.
And warm colors more generally connote
feelings of urgency.
When using combination, these colors can
make us feel like the only possible time
to stop for a hamburger or get gas is
right now.
So, returning to my career,
for a long time, the tools of my trade
were exclusively the provenance of
lighting designers. Theatrical lighting
fixtures are expensive and efficient
LEDs either weren't yet invented or
weren't widely available.
But, that's changed in recent years.
Home improvement stores have always had
aisles full of lighting, but the
contemporary variety is pretty
extraordinary.
Chances are excellent that many of the
people in this room can change the color
of at least some of the lights in your
home using an app on your phone.
For the first time I'm aware of, it's
possible to easily select the color
temperature of your car headlights.
And that control is just in lighting.
You also have enormous color control of
the other items in your daily life.
That shift in availability means that
it's now not just possible, but
practical for you to curate your
personal color space based on a variety
of emotional, physical, and work needs.
So, with that in mind, here are three
ways you can leverage color in your
personal life using items you already
own
or things that are relatively
inexpensive and easy to get hold of.
Looking to spark attraction?
Try red.
Wear a red outfit, red lipstick, even
red nail polish.
Red's attractive qualities are
universal, and they seem to apply
equally to men and women.
Conversely, avoid red if you're working
on difficult tasks like studying.
Exposure to red and other saturated
colors seems to limit achievement.
Turn the lights to blue if you want to
relax, have just been in a stressful
situation, or want to evoke the outdoors
while you're inside.
But, be cognizant of the time of day.
Exposure to blue light can trick the
brain into thinking that it's morning,
which suppresses melatonin production,
and that can keep you awake. That's the
same reason you shouldn't spend time
with your screens right before bed.
Read and study under warm or neutral
white light.
Paint the rooms where you work white or
light yellow.
And always take notes on white or light
yellow paper.
These colors increase visual contrast
and seem to stimulate brain activity.
The colors surrounding us have a
meaningful impact on our daily lives,
and with just a little bit of context
from science and culture, we can
manipulate them to improve our overall
well-being.
Exactly like lighting a stage, the
colors we choose carry meaning. So,
select them with care to shape the way
you want to feel,
think, and live. Thank you.
