Materials that can undergo a reversible color change, upon the application of an external stimulus, are technically known as chromic materials. Research into the application of such materials has been extensive due to the ability of color change to effectively convey important information and therefore have been used in the industry to fulfill certain applications. Since they have the capability to change their colour, they have been used in some hazardous applications, medical applications and some may serve pure artistic statement. Each of these chromic materials react to external stimuli in a very different way. Materials that display chromic properties are classified by the type of stimuli that induces their color change. This paper aims to introduce the different types of chromic materials used within the industry and to demonstrate how far they are known within the Egyptian community through surveys.
