LAB color space is the engine that powers color management

Video Transcript:

The LAB color model is a three axis color system and LAB colors are absolute, meaning that the color is exact. It’s what’s known as device independent; meaning that the LAB color space is the only way to communicate different colors across different devices. An object’s color is measured in LAB color with a spectrophotometer.

00:23 It is a three axis system. The first axis, the L-channel or Lightness, goes up and down the 3D color model and it consists of white to black – and all of your gray colors will be exactly right down the center. All neutral colors will be relatively in the center of this axis.

00:43 The A axis, goes from cyan color across to magenta/red color. And the B axis goes from blue to yellow. So within this area we’re going to plot visual or reproducible colors based on the gamut or the profile of the device we have.

01:05 So we’re going to turn on the sRGB color profile. Most monitors will display in sRGB and sRGB is preferred for any type of internet or web application. We’ll get this thing spinning here and you can see the volume of the colors that you can reproduce from this additive color model. Obviously since dealing with projecting light, they’re very bright colors and they’re very saturated.

When to use LAB color space

– Matching paint colors to printed media

– Matching fabric colors in a catalog or website

– Communicating your favorite Pantone color to another media form

– LAB color space is the back-bone of all color management between devices in the color workflow

  2. Hi Rick

    Thank you very much for a very informative article on LAB colour. I fortunately discovered LAB a week ago and I am very excited about it. Is LAB suitable for landscape photography? How many top landscapers use LAB? Where can I find more info about LAB?

    Thanks for yoyr time and attention.

  3. great video! I saw one slight error, though: at around 1:10, the LAB values for the blue pop up. It should say b: -66, not b: 66.
