This post is for #paintwithdow in the #art section. It features a project using cells separated in *L*a*b color mode. Each cell is divided into 5 levels, gradually increasing from light to dark—this applies to all three channels: *L, *a, and *b.

You’ll start by painting three canvases in grayscale using only black and white paint, representing each of the three channels. After scanning the finished canvases:

The *L scan is fine as-is—*L represents lightness, like a grayscale image.

For the *a and *b scans, you’ll need to edit them: darken the highlights slightly (close to midtones) and lighten the shadows slightly (also close to midtones).

Once the edits are complete, compose the three grayscale scans back into a single color image using GIMP. The final result will look amazing! I'll walk it through with you.
---------------------------
L*a*b (Lab) is a color mode that represents how humans perceive color. It has three channels:

L* = Lightness (from black to white, like a grayscale)

a* = Green to Red axis

b* = Blue to Yellow axis

It's designed to be more perceptually accurate than RGB, making it great for color correction and editing.
