How to use Show LCH Colors of Image
- 1. Upload the image to analyze. Add any image file. It's converted into LCH, the cylindrical form of CIELAB that expresses color as luminance, chroma and hue instead of L, a and b axes.
- 2. Review the luminance, chroma and hue panels. There are no settings to adjust. Each of the three components renders as its own grayscale strip so you can see how perceived brightness, colorfulness and hue vary across the photo.
- 3. Download the channel strips. Save the file with all three LCH panels together for side-by-side inspection.
When to use Show LCH Colors of Image
Show LCH Colors of Image breaks a photo into its luminance, chroma and hue components, the polar version of LAB used in modern CSS color functions like lch() and oklch(). Use it to see what each of those three values actually represents on a real image.
- Understanding a CSS lch() or oklch() value. You're adopting the newer CSS color functions and want an intuitive sense of what changing chroma versus hue does. Viewing the panels for a sample photo makes each axis concrete.
- Checking colorfulness independent of hue. You want to know which parts of a photo are the most vivid regardless of what color they are. The chroma panel isolates exactly that, ignoring hue entirely.
- Comparing LCH against LAB for the same photo. Understanding the relationship between LAB's a/b axes and LCH's chroma/hue is easier with matching visuals. Generating this LCH breakdown alongside the LAB one clarifies how they relate.
