How to use Show LAB Colors of Image
- 1. Upload the image to analyze. Add any image file. It's converted into CIELAB, a color space designed so numerical distances match perceived color differences.
- 2. Review the L, a and b panels. There are no settings to adjust. The L channel shows lightness while the a and b channels capture the green-red and blue-yellow color axes, each rendered as a grayscale strip.
- 3. Download the channel strips. Save the file with all three LAB panels together for a closer look at each axis.
When to use Show LAB Colors of Image
Show LAB Colors of Image splits a photo into its CIELAB lightness, a and b channels, a color space built specifically so that equal numeric differences correspond to equal perceived differences. It's the model behind many professional color-matching and comparison tools.
- Isolating lightness for a color-matching workflow. A print or fabric color-matching process relies on LAB's separation of lightness from color. Viewing the L channel alone on a sample photo shows exactly what that separation looks like.
- Understanding a color-difference calculation. A tool or script computes color distance using LAB values and the results seem off for a particular image. Viewing the a and b channel panels helps sanity-check what those axes actually represent for that photo.
- Studying red-green and blue-yellow balance. You want to see how a photo's colors sit along the two perceptual color axes independent of brightness. The a and b panels show exactly that split.
