Transcript of Color Psychology

This experiment will investigate how different colors influence appetite.
Can a color make you hungry or happy?
Ever wonder why so many restaurant advertisements are predominantly red and yellow? There is in fact a science behind that.
What I knew before...
In conclusion, my hypothesis was proven correct based on the evidence and data recorded throughout my investigation and experiment.


Color does in fact have an influence on your appetite and hunger. Red is ultimately the most effective while blue seems to be the detterent for hunger.
If an experimental group of students view slides of particular foods with different color backgrounds, then they will react differently to each presentation with different levels of hunger and emotions but the foods with red backgrounds will spike hunger levels and blue will deterr it because based on extensive color psychology, different colors affect our decisions, behavior, and appetite.
Revisions to procedure:
If I had the option to revise my procedure and do it again, I would widen my experimental groups to have better results. And I would also conduct the experiment at least twice to acquire more accurate results.
The importance of Color Psychology
Background information: Its called Color Psychology. There is plenty of scientific evidence suggesting that color has a unique ability to sway our desire for certain objects like food. This experiment will look at how colors affect hunger.
To investigate how different colors influence appetite and behaviors.
Software for presentation design (power point)
Electronic images of many types of food
Test subjects (control and experimental groups)
1. Create survey to give to test subject that analyzes their current food preferences.

2. Design a presentation that has a single image of a food on each slide.

3. Gather test subjects in a room 1-2 hrs before lunch time.

4. Distribute surveys.

5.Show test subjects presentation with one color background
6. Ask subjects to repeat survey afterward.
7. Repeat test but with different colors each time to see variations (include white).
Evaluation of Procedure
Quantitative Data
Qualitative Data
According to recent studies in psychology, color is a major influence in many of our general decisions. Therefore it is important to understand the effect color has on us so we can exhaust potential controlled uses and advance because of it.
Color psychology correlates to real life because the more we understand it the more we can use it as a technique or method. We can twist and morph it to our advantage. For ex. since blue acts as a deterrent for hunger, dieters will sometimes paint their kitchen blue or have blue plates.
Questions for further research:
How many experiments or studies have been done that wield the same results as me
How far back does color psychology go
Does color psychology only apply to emotions and appetite? Or can it be applied to major decisions and such?

Major discovered...
The Question/Problem of this experiment is whether or not color influences our appetite or plays a role in our behavior.
The Big Question:
Mathematical Analysis:
If some colors act as a deterrent for appetite while others act
as an potentiator, then such colors such as red will increase appetite
and colors such as blue will diminish hunger. The percentage of increased hunger levels in reaction to red will vary between people but will be substantial to the decreased levels of blue which would be 1/3 of the hunger levels of red.
My hypothesis was proven correct by the data collected during my experiment. With the slides that had red backgrounds, hunger levels increased the most (from 78% to 98%) and with blue, the hunger levels either remained the same, or faltered slightly. This proves that color does in fact influence our appetite and my hypothesis that blue is a deterrent while red is a potentiator.
Color impacts our decisions and perception of certain things in some way.
Red and yellow are used in advertisements in order to attract customers.
Studies were being done in a potential way to use colors for hypnotism and positive reinforcement.
Angela Wright made a major breakthrough in our understanding of colour psychology with her discoveries about how colour really works, in the late 1970s/early 1980s.
In the early 1990s, it was discovered that there are mathematical correlations between colors within each group, when classified in line with the theory, that do not exist
between colours
from different groups. This
established that
objective color harmony is
a scientific reality.
to Prof. Mehta, people
exposed to more red are more
careful as it reminds
us of stop signs, stop lights, ambulances, etc.

Additional Information:
Even though color psychology is a fairly new field, the world is adapting quickly to its rise and it as accepted in the general population among physicists, psychologists, and more.
Many books have been written on the topic, many experiments and theories proven, and there are even courses on understand color phschology.
