With the help of the special card and application, we can find out which color of the Pantone scale the given tone matches the most within 25 seconds.
No one, be it a designer or a layman, has the entire Pantone scale in their head. To help us identify colors and avoid clumsy tone descriptions, Pantone releases an easy-to-use application.
To use the application, first we have to purchase a Pantone card, which is the size of a regular credit card, for USD 15 (available for order on the site of the company), which we have to place on the surface of the color we are looking for. Then we can start using the app by adjusting our phone on the card, and after waiting 25 seconds, the app tells us the color that matches it the most.
