TOPIC OF MY REPORT:
The impact of light and colour ON
psychological mood.
INTRODUCTION:
The aim of the study was to determine whether indoor lighting and colour
would have any systematic impact on the mood of people working indoors.
Earlier studies have mostly focused either on light, colour or windows in
laboratory settings. The workers’ mood was at its lowest
when the lighting was experienced as much too dark. The mood then
improved and reached its highest level when the lighting was experienced as
just right, but when it became too bright the mood declined again. The results also
indicate that the use of good colour design might contribute to a more positive mood.

Pyscological effect of light:

Even increase cognitive Light creates more than just visual effects (image, shape, intensity,
perception, contrast, etc.); it also has biological and psychological effects that can impact the
health and wellbeing of humans. When light biologically impacts us, it can improve or disrupt
our sleep, cognition and overall wellbeing. It can improve mood and stabilize our circadian
rhythms, helping us get a better and deeper nights sleep. Psychologically, light can decrease
depression scores and performance such as reaction time and activation. Light helps us get a
better view on the world. It also helps shape our perception of it. By properly understanding how
light impacts our moods and behaviour, we can create spaces enabling us to be more creative,
energetic, and productive. If you notice your mood start to shift upon entering your home or
office, you may want to rethink its lighting. Our bodies take cues from our environment, light
and sun. We need sunlight to regulate our circadian rhythm, which acts as our body’s internal
clock. For instance, when a person is jet-lagged, it is mainly because their circadian rhythm is
thrown off. The body may think it’s eleven 11 pm when it is actually 3 pm. Lighting can disrupt
our body’s natural patterns, leading to changes in our energy levels, mood, and even the
hormones we produce. We rely on that internal clock to regulate inner functions, and our
lighting plays a huge role in this. Here are the different ways in which lighting can affect our
mood and behaviour. Light effects our mood, behaviour, and overall well-being. However, its
wavelength and amount have different functions and effects upon the brain, including the
regulation of feelings and thoughts. This means that simple adjustments in your home or office
lighting can make a world of a difference to how a person feels and thinks.

PYSCOLOGY EFFECT OF COLOURS:

colors influence our lives more than we can think. They interact in decision making, in the
storage of memories, in emotions, and our state of mind in general. It is possible that we have a
preference for color and that it dominates our clothes for what it makes us feel.

. There are conflicting opinions on the impact of color. Of course it is natural to think
that
there is a connection between color and mood, because we prefer to live in a room
with
"vibrant color " than between four gray walls! We also know that certain wavelengths
of
sunlight (colors) exert an influence on our mood. Colors are nothing just a light waves
with
certain wavelengths: some studies seem to have found a link between color and mood.
We
must recognize that our perception of color is completely individual. A environment can
result relaxing for any person, but stressful for someone else. Therefore it is difficult to

generalize the effects of certain wavelengths. Despite the general lack of research in this

area, the concept of color psychology has become a hot topic in marketing, art, design,
and
other areas. Artists and interior designers have long understood how color can
dramatically affect moods, feelings, and emotions. It is a powerful communication tool
and
can be used to signal action, influence mood, and cause physiological reactions.

Here is breakdown of how different interior colours affect our moods...

1. Blue Blue is a very calming colour that can make you feel centred, relaxed and serene.
It is known to help lower blood pressure, clear the mind and help steady one's
breathing.

While blue rooms are lovely to lounge and rest in, it is important to note that pastel blues can
come across as very cold and chilly. Light, warm blues are great and are easily balanced with
warm hues and furnishing.

2. Yellow
Kitchens are great rooms to paint yellow as it brightens your mood and increases your energy
- something we usually all need in the morning as we make our way to the kettle. Yellow can
catch the sunlight and leave you with an uplifting feeling of joy and liveliness.
3. White
White instils the fear of dirt in even the messiest of people. But painting
your walls white or off-white is a great way to help make your home feel
more spacious and open and the people within it more neutral. Not
necessarily an energy nor calm inducing colour, white gives a happy
medium that leaves you feeling clean.

White rooms give an automatic feel of cleanliness and purity. The colour
white itself stands for protection, innocence and goodness, to name a few.

Painting your ceilings white or off white are easy options that go with just
about every colour and gives the illusion that the ceiling is higher and the
room is bigger.

4. Green
This is a great colour for your home office as it symbolises prosperity and helps to reduce
anxiety. It is one of the most restful colours for your eyes and is known to be restorative, mind-
clearing and encourage composure.

For those who love the outdoors, it also gives an outdoorsy, natural feel - much like blue speaks
to those whose hearts truly lie by the water.

5. Purple
Purple is a rich, dramatic colour that is historically the colour of royalty and luxury. Deep
purples give off a very romantic, mysterious and luxurious vibe and are great for
sparking creativity. While deep purples aren't the best for the bedroom, where you want the
mind to relax, lighter purples such as lavender and lilac are better options as they are calming
and light.

6. Orange
Orange is a very exciting colour that brings a burst of energy and
enthusiasm. It's a great colour to exercise around, but not so good for living
rooms or bedrooms where we want to wind down.

Orange can also stimulate your appetite so, if you're trying to be a little
more healthy and calorie conscious, we wouldn't recommend this colour for
your kitchen.
7. Red
While many people link red to romance and roses, it is also linked to hostility and rage. Red is
known to raise blood pressure, heart beat and irritability.

It's a great colour to use for socialising – especially around Christmas – and we would suggest
that you keep this colour to social rooms as opposed to rooms that are meant to be
for relaxing.

8. Pink
Interestingly enough, there is such a thing called the Pink Effect. This is when exposure to large
amounts of pink can have a calming effect on the nerves and helps relieve feelings of anger,
aggression and neglect.

Pink has the opposite affect to its primary colour, red, as the longer you are exposed to it, the
calmer you will become. Lighter pinks are great for childrens' rooms and promote feelings of
love, playfulness and kindness.

LITERATURE REVIEW:
light and colour effect a lot on pyscological impact on human behavior .when we sleep in bright
light our brain effects alot .in dark colour we feel warm in light colours we feel cool and openess
effect.mostly in eating places we use bright colur like red , orange , yellow that appetite our
hunger. In gym areas we use red orange colour for energy.mostly in dim light and dark colours
we feel sad . light effect our eyes . in bright light human feel anger ,
headache ,frustration,depression.while study in dim light our eyes faces bad effect.

Colours may just seem simple and unimportant, but they affect our daily lives more than
we
may know. If someone is feeling angry, it could just be because they are angry, or it
could
be perhaps that they are surrounded by or looking at the color red.
-‐ According to Johnson (2007), color does affect mood by producing certain chemicals
and
stimulating different feelings such as hunger. For example, blue can make one feel calm
because it releases calming chemicals, and red can make one hungry because it is an
appetite stimulant. Yellow can make one feel irritated, and it is a fact that people lose
their
temper most in yellow rooms. However, pink is tranquilizing and can make one feel
weak.
In conclusion, Johnson says that depending on the color, one’s body can do things (like
producing chemicals) that cause a certain emotional reaction (mad, sad, etc.).

light may There is some evidence that the colours of an interior space might influence the
psychological mood of individuals in that space (Ku¨ ller and Mikellides 1993). Lightness,
hue and saturation might be of importance, as might the combination and distribution of
the colours in the interior space. A number of studies have compared the impact of
‘warm’ and ‘cool’ colours (e.g. reds and blues) (Stone 2001, 2003). Letting his participants
work in either a red or a blue office space, Janssens (2000) found an interaction between
psychological mood on one hand and performance on the other. Comparing nine
monochromatic office colours, Kwallek et al. (1996) found that saturation was a salient
predictor of differences in mood between males and females.
