Convert the output image of each LAB channel to gray tones.

What Is a LAB Image Color Extractor?

This tool decomposes the image into LAB color components. LAB is a color space commonly used in color science and image editing. This program allows you to break down the image into LAB color components. The first component is L (Lightness). This channel represents the image's brightness, ranging from 0 (black) to 100 (white), controlling the image's luminance. The second component is A (green-red axis). The A channel represents the spectrum from green (-128) to red (+127). Negative values represent green tones, while positive values represent red tones. The third component is B (blue-yellow axis). The B channel represents the spectrum from blue (-128) to yellow (+127). Negative values represent blue tones, while positive values represent yellow tones. By separating one component from the others, the resulting image shows the properties of only the specifically chosen component. You can separate multiple components, compare them, and optionally convert them to grayscale tones. Image-abulous!

Print a Lightness Channel

In this example, we demonstrate what the lightness channel looks like when separated from the other channels in the LAB color space. It appears as a black and white representation, with brighter areas rendered as white (light gray) shades and darker areas as black (dark gray) tones. (Source: Pexels.)

Decomposes LAB Channels

In this example, we decompose the image of a flower into three LAB color space channels. The first image displays the lightness channel, the second image displays the green and red tones (channel A), and the third image showcases the blue and yellow tones (channel B). (Source: Pexels.)

Print LAB Channels in Grayscale

This example demonstrates how the extracted LAB channels appear in grayscale space. Due to the brightness of the yellow color and the saturation of the pink hue, it can be challenging to discern the extent of color information in the extracted A and B channels. When applying the grayscale filter, object shapes in the image become clear and distinct. (Source: Pexels.)
