What is Delta E color deviation?

When choosing to buy a graphic-technical computer monitor, you may have heard the term Delta E (also known as Delta E color deviation). So how important and influential it is to monitors in general and professional graphics monitors in particular, let’s find out in this article!

What is Delta E color deviation?

Delta E (dE) is an index measuring the distance between two colors created by the Commission Internationale de l’Eclairage to determine the difference between two colors on the screen to evaluate. the optimal level of colors on the screen compared to the original color. This measurement provides detailed information about the accuracy of color on the screen of devices such as: PC, laptop, projector, printer, …

The smallest color difference that humans can see is 1.0 dE , errors less than 1.0 dE are usually considered invisible, so when choosing technology devices such as monitors, projectors, Delta E levels closest to 0 is the most optimal choice for users.

On a scale from 0 to 100 points (0 points means no color difference, 100 points means complete deviations) Delta E is divided into value ranges:

• Delta E less than or equal to 1.0: Almost exactly the same as the original color.
• Delta E is less than or equal to 1-2: Almost the same as the original color but can be observed if you look closely
• Delta E less than or equal to 2 – 10: The difference from the original color can be easily seen.
• Delta E less than or equal to 11 – 49: Almost the same as contrasting color.
• Delta E less than or equal to 50 – 100: Completely contrasts with the original color.

The importance of Delta E in graphics

This deviation is often noticed by graphic technicians or photographers because it is a standard to determine color accuracy, based on it, evaluates the ability to display color on industrial devices. technology, thereby making a decision whether to choose that product or not. Professionals need to make sure that the colors they see on the screen are as close to reality as possible so that when working on a project on multiple monitors, there is no problem of distortion.

How should I choose a device with a Delta E level?

The average deviation value in current laptops is dE less than 3 . Owning a graphic-technical laptop for graphic and creative needs, the dE deviation of less than 2 is reasonable, the color on your laptop will display the same color as the original color. However, with economic conditions allowing, a monitor with a dE index less than 1 will be the superior choice for you.
