The word "delta" is derived from the Greek and represents the incremental change of a variable. "Delta E" as a whole means a difference in sensation. In color science, Delta E is the measure of change in the visual perception of two colors. Delta E values range from 0 to 100. When the Delta E between two colors is 0, they are the same uv =p(∆L∗)2+ (∆u∗)2+ (∆v∗)2. It shows that the distance of color p(∆u0)2+ (∆v0)2= 13 corresponds to the same ∆E∗. uv as the differ-. ence in brightness ∆L= 1, which is Sunlight exposure can have harmful impacts on carbon-based materials such as coatings, polymers, textiles, and many others.

ASTM D2244 is a standard test method for calculating color differences from instrumentally measured color coordinates. Effectively a delta E* tolerance value defines an acceptance sphere around the standard or target color. The lower the delta E* value is, the closer the sample is to the standard. A delta E* value of 0.00 means the color of the sample is identical to the color of the standard. Please note that while CIE L*, a*, b* are being used in this example De bus die verbindt.
