What’s the Difference? Using Improved Color Difference Equations
Differences between colors can be described using dL*, da*, and db* values, but for simplicity a single value describing the overall magnitude of the difference between two colors is preferred. This is referred to as the ΔE or dE value, the simplest form of which is the dE* value, calculated as the distance between two colors plotted in L*a*b* space. Unfortunately this color space is not visually uniform, resulting in the need for individual tolerances for every color. This webinar will explore alternate color difference equations, with the goal of calculating dE values that are visually uniform for all colors, allowing the use of a single tolerance for all color standards.
Attendees will develop an understanding of:
- The non-uniformity of CIEL*a*b* color space and the dE* calculation
- Benefits of improved color difference equations
- The dEcmc, dE94, and dE2000 calculations and their implications in color space
- Benefits of a single tolerance for all colors
