How to use Show HSL Colors of Image
- 1. Upload the image to analyze. Add any image file. It's converted into the HSL color space, the same model used by the hsl() function in CSS.
- 2. Review the hue, saturation and lightness panels. There are no settings to adjust. Each of the three components is rendered as its own grayscale strip so you can see how they vary across the photo.
- 3. Download the channel strips. Save the file with all three HSL panels together for a side-by-side view.
When to use Show HSL Colors of Image
Show HSL Colors of Image splits a photo into hue, saturation and lightness panels, the color model behind CSS's hsl() function. It's useful for anyone working with HSL values in stylesheets who wants to see what each component actually represents on a real photo.
- Understanding a CSS hsl() adjustment visually. You're tweaking a design's colors using CSS hsl() values and want a concrete sense of what changing lightness versus saturation actually does. Viewing each panel separately on a sample image makes the difference obvious.
- Checking which region is washed out. A photo looks a bit dull overall and you want to know if it's a saturation problem or a lightness problem. The saturation panel alone will show which areas have lost color intensity.
- Building color-space teaching material. A tutorial or internal doc explaining HSL to a design team benefits from a real image broken into its three channels rather than an abstract diagram.
