Identifying Color Differences Using L*a*b* or L*C*H

  1. The L*C*h color space is similar to L*a*b*, but it describes color differently using cylindrical coordinates instead of rectangular coordinates. In this color space, L* indicates lightness, C* represents chroma, and h is the hue angle. Chroma and hue are calculated from the a* and b* coordinates in L*a*b*
  2. a*: Red/Green Value. b*: Blue/Yellow Value. As an example, see figures 17 and 18, showing the color-plotting diagrams for L*a*b*. The a* axis runs from left to right. A color measurement movement in the +a direction depicts a shift toward red. Along the b* axis, +b movement represents a shift toward yellow. The center L* axis shows L = 0 (black.
  3. CIE *L*a*b envisions a three dimensional space, with three axes, represented in Figure 2 (Eye-Colour. 2002) *L is the light and dark axis. It can be thought of as the average value of a spectral curve, with 0 representing no reflection (black) and 100 representing high reflection (white)

The CIE 1976 L*a*b* color space (also referred to as CIELAB) is one of the most popular color spaces for measuring object colors. It was defined by CIE in 1976 for color communication and is widely adopted today in many industries for color control and management.

Created in 1976 by the International Commission on Illumination, the value expresses color as three values. Hunterlab has an extensive article on the topic, but the general elements are as follows The L*a*b* color space is derived from the CIE XYZ tristimulus values. The L*a*b* space consists of a luminosity 'L*' or brightness layer, chromaticity layer 'a*' indicating where color falls along the red-green axis, and chromaticity layer 'b*' indicating where the color falls along the blue-yellow axis

The LAB color space goes about defining colors differently. Whereas RGB defines color by a combination of red, green, and blue values of different shades, LAB uses three different channels. They are: Lightness, something called the A Channel, and the B Channel. Hence, Lightness, A Channel, and B Channel are shortened to L-A-B, LAB The L.A.B. sound is one which has seen them quickly become a fan favourite on the New Zealand live circuit - trademark Kora grooves combining with Adams - Tamatea's reggae/dub experience, and Shadbolt's blues roots to create a sound entirely their own.

The CIE 1976 L*a*b* color model is based on the CIE 1964 color model which was further enhanced because of two problems with the specification of colors in terms of tristimulus values and chromaticity space.Firstly, this specification is not easily interpreted in terms of the psychophysical dimensions of color perception namely, brightness, hue, and colourfulness


The values can be pretty much anything as it is dependent on your reference white point. In MATLAB, I believe the reference point is D50.If you want to see what the dynamic range is, you can iterate through all possible RGB values (2^24), convert each into their Lab* counterparts, then find the min and max of all channels.To start, L* definitely lies between [0,100] But in Lab you have two complementary colors on the same scale. This means that the a and the b are not representing one color but an axis of complementary colors. Two colors that, if mixed in this model, the cancel each other and make a neutral gray. So the scale is not 0 to 255 but -128 to +128 where the 0 is at the middle indicating that. In particular, the L*a*b* system can be plotted as a sphere that contains hundreds of thousands of different colors. Each color has its own unique point within the sphere. The Delta-E Measurement.

The L*a*b* colorspace was devised in 1976 (let's just call it Lab for short) and, at the same time delta-E 1976 (dE76) came into being.

The scales are three dimensional and the mathematical difference between any two points is described as DELTA E. This DELTA E is an attempt to state in one number the color difference between two samples
