FQC/FIRST Tech Focus: CIELAB Is Icky! Do We Have Any Other Choice?

CIELAB is the ubiquitous and indispensable tool that color management is built upon. We use it to measure, specify and apply tolerances to color. And yet, 48 years ago when it was created, it was widely recognized to be less than perfect.

The biggest problem is that it is not a uniform color space (hence the need for complex color difference calculation). In addition, colors with identical hue angles are not necessarily perceptually the same hue. Changes in CIELAB values under different illuminants are largely due to a questionable decision that was made in 1931. And, gosh darn it, the a* axis points toward magenta, and not to red as we have been led to believe.

Join John Seymour as he explores if, after 48 years of slide rule pushing, are there any better alternatives?
