Colors may also change when the area is exposed to heat. Other modern paints may change color when treated with some chemicals. 

Some paints react to electricity by changing their color. When exposed to an electromagnetic force, the spaces between the particles changes, making the shade of the paint change. These are called electrochromic paints and they are used by automobile makers such as Nissan.

Electrochromic paint can be used for plastic substrates or synthetic materials. Special dyes are treated with electric current, leading to their change in color. You can see this type of paint color change on airplane windows at a touch of a button.

One of the popular makers of paint that change colors is Chroma Flair. This paint system is used in painting cars but can also be used for walls.

A paint that changes color with light is called a chameleon. As the name implies,  it changes color when it is hit by light.

The paint contains very thin flakes of different colors that interfere with UV rays to produce several colors. It is also known as the property of iridescence. As the viewer moves and changes position, the colors would look different.

Photochromic inks and paints change color when exposed to light or ultraviolet rays of the sun. They also react to black light. When used indoors, they show no color. Yet, when they are brought outside, they have different vibrant colors.

To make the color more vivid, expose the ink for 15 seconds under direct sunlight. Once you take it in a place without sunlight, the ink becomes clear.

Ink may come in liquid or powder form. They are used to make markings. Graphic designers also use them in their works.Some inks can change color under different temperatures. They are also called smart inks.

Labels have adhesive backs that can be used to place them on a surface. When there is a change from cold to hot temperature, it changes its color. As heat affects the molecular component of the paint, it changes colors. The paint exposed to heat is now absorbing heat differently.

With thermal paint, the light reflected is less, reducing the temperature inside the building. Because it serves as a good insulator, it costs more than regular paints. Its price is $320 or more per liter.

How Long Does Thermochromic Paint Last

Thermochromic paint can only last for four to six months. This is because of its high exposure to AUV. To prolong its life, you can use a clear coat that contains an AUV protection formula.

Thermochromic paint changes color with temperature. If you have a patchy orange car, you can pour cold water on it to change it into a stunning bright orange car.
