Introduction

Have you ever wondered if the color of font makes a difference in how quickly you can read something? Well if you have this is the project for you. The purpose of my project is to see if color affects readability, so keep reading and see my results.

You can use color to help you identify objects. According to Newton, although color isn’t inherent in objects it is on the surface of an object which reflects some colors. The property possessed by an object produces different sensations on the eye, as a result of the way the object reflects or emits light. But it is important to note that black objects absorb all colors so no light is reflected (Colours of light — Science Learning Hub.)

It is of primary importance to recognize that objects do not have color, they reflect wavelengths of light that is interpreted as color by the human brain. Wavelengths can range from 400nm-700nm...that's the end of the red spectrum to the end of violets. The human eye is most sensitive to light at a wavelength of 55 nanometers - which is a bright green. White contains all of the colors in the rainbow because it contains all wavelengths (How Humans See In Color).

In addition, there are 3 types of cone shaped cells and they all are sensitive to the wavelength of light. All of these cells are working with the nerve cells which gives the brain information to interpret and identify colors. Cones are concentrated in the middle of the retina. There are 6 million cones in each eye. Cones have fast response (aka short interrogation time), are selective, have low sensitivity, and contain 3 types of pigment. Cones show all the colors of the rainbow and use short, medium, and long wavelengths.(Rods & Cones)

Did you know that cones respond differently to light of different wavelengths therefore making them responsible for color vision? Color vision means the ability of animals to perceive differences between light composed of different wavelengths independently of light intensity. It can also be the ability to make discrimination based on the wavelengths compostion of light independent of its intensity. There are 3 types of photopigments: red, green, and blue, they are all sensitive to different wavelengths of visible light. There are 3 types of the color reception -response curves. Color blindness happens when one or more the cones aren't working properly. red -green color blindness is most common. Men are more prone to color blindness than women. There are 3 types of the color reception -response curves. (How Humans See In Color)

There are 2 types of cells that respond and identify colors - rods and cones. There are around 120 million rods in your eyes and all of them are more sensitive than cones. Rods are sensitive but not to color. They are activated in dim/darkish light. 110 million in each eye. Rods are high sensitivity, slow response (aka long interrogation time), not selective, and one type of pigment. Rods can only see black, white, and gray.They contain no actual colors from the rainbow. When rods are activated you see different shades of gray - no color. (Rods & Cones)
