This experiment was performed to find out how different colors affect the blood pressure of a person.
Persons who have been exposed to warm colors such as yellow or red will have increased blood pressure compared to persons who have been exposed to cooler colors such as green or blue.
Colors and mood
The influence of color on a person mood and consequentially their blood pressure, is determined by their psychological and cultural background. The behavior or emotions commonly associated with some colors are listed below. Such associations are based on cultural beliefs and are not necessarily based on scientific truths.
Blue is a cool color. It is calming and soothing to a person. It makes a person confident and secure.
Red is a warm color. It is known to increase a person heart beat rate and blood pressure. This color also represents passion, strength and danger.
Black represents elegance and class. This color has long been associated with death in many cultures. In such cultures, black represents emptiness and darkness.
White is the color of purity and peace. This color also represents cleanliness and sterility.
Green is also a cool color. It helps to keep a person calm. This color represents nature and intelligence.
Yellow is a warm color representing sunshine and happiness. However yellow has been known to also invoke anger.
Psychology, blood pressure
The materials required for the experiment:
You should observe that the participants' blood pressure increases after they have been made to stare at the red and yellow screens. Other colors do not lead to significant changes in blood pressure.
The hypothesis that the colors red and yellow will cause a person's blood pressure to rise, is proven to be true. The calmer colors of blue and green, and the neutral colors of white and black did not show any significant effect on blood pressure.
The experiment can also be performed using different colored light bulbs to light up the room and to check blood pressure.
