**Delta E*** (Total Color Difference) is

**calculated**based on

**delta**L*, a*, b* color differences and represents the distance of a line between the sample and standard. Effectively a

**delta E*** tolerance value defines an acceptance sphere around the standard or target color.

Similarly, what does L * a * b * stand for?

The CIELAB color space (also known as CIE

**L*a*b*** or sometimes abbreviated as simply "Lab" color space) is a color space defined by the International Commission on Illumination (CIE) in 1976.Also, what is Delta value in printing?

**Delta**E (∆E)

**Delta**E is defined as the difference between two colors in an L*a*b* color space. As the

**values**determined are based on a mathematical formula, it is important that the type of color formula is taken into account when comparing the

**values**.

How do I convert RGB to XYZ?

Linear

For example, if your values are in the range [0, 255], you must first divide each by 255.0. The output **RGB to XYZ****XYZ**values are in the nominal range [0.0, 1.0]. The

**XYZ**values will be relative to the same reference white as the

**RGB**system.

What is Delta value on color?

**Delta**E is a metric for understanding how the human eye perceives

**color**difference. The term

**delta**comes from mathematics, meaning change in a variable or function. The suffix E references the German word Empfindung, which broadly means sensation. On a typical scale, the

**Delta**E

**value**will range from 0 to 100.
