General Medicine & Health Science Fair Project

Color and Blood Pressure

Color and Blood Pressure | Science Fair Projects | STEM Projects
We're going to find out if colors like red and yellow can make our blood pressure go up, while colors like blue and green can keep us calm.


The hypothesis is that 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.

Method & Materials

You will need 10 male and 10 female participants of the same age, a computer, and a portable (wrist) blood pressure monitor. You will measure the participants' blood pressure before and after they stare at the computer screen for 3 minutes. The screen will show different colors like blue, red, black, white, green, and yellow.

The experiment showed that the participants' blood pressure increased after they had been made to stare at the red and yellow screens. Other colors did not lead to significant changes in blood pressure.

Why do this project?

This science project is interesting because it explores how colors can affect our moods and health. It can also be useful in the advertising industry, where colors are used to create specific moods.

Also Consider

Experiment variations include using different colored light bulbs to light up the room and to check blood pressure, or checking the pulse rate instead of blood pressure.
