What is HSL Colour Adjustment and When Do You Use It
HSL colour adjustment is a selective editing tool that lets you modify the hue, saturation, and lightness of specific colour ranges in a photo independently. You use it when you want to warm up skin tones, desaturate a distracting red object, or shift the green in a landscape without affecting the entire image.
What HSL Adjustment Does
HSL stands for Hue, Saturation, and Lightness. Each slider targets one component. Hue shifts the actual colour along the spectrum, saturation controls how intense or muted it appears, and lightness brightens or darkens it. The key difference from global brightness or saturation sliders is that HSL works on colour ranges. You pick a colour band (reds, oranges, yellows, greens, cyans, blues, or magentas) and only that range changes. The sky stays blue while you warm up the sunset orange. Your subject's skin tone shifts warmer without affecting their clothing. It's surgical rather than blunt.
When Professional Photographers Use HSL
Portrait retouchers use HSL to warm skin tones without affecting the background. Landscape photographers use it to intensify greens or shift a dull sky to something livelier. Product photographers use HSL to make reds pop on packaging or desaturate competing colours. Food photographers use it to warm up plate colours or cool down a bluish cast. Wedding photographers use it to correct white balance on specific colour elements, like making florals more vibrant without blowing out skin tones. In short, any time you want to fix or enhance one colour family without a global adjustment, HSL is your tool.
HSL in Cleanr: AI Pro
Cleanr by MRVL includes HSL colour adjustment as part of the AI Pro tier (£12.99/mo or £99.99/yr). Once you've cleaned your photo using Cleanr's core tools, like object removal or background cleanup, you can fine-tune colour with HSL sliders. This works well for faith creators and small business owners who shoot product photos or portraits for social media and want professional colour grading without learning desktop software like Lightroom. The adjustment sits alongside other advanced controls like tone curves and selective adjustments, so you can build a complete edit within one app.
HSL vs. Other Colour Tools
Cleanr also includes global saturation and warmth sliders in the free tier, which are simpler but affect the entire image. HSL gives you precision. If you only need to brighten or cool down a photo overall, the basic adjustments are faster. If you're targeting a specific colour, HSL saves time and looks more natural. The AI Pro tier also includes tone curves for pixel-level control and selective adjust, which lets you brush a mask over regions and adjust brightness, contrast, or saturation just in that area. Different tools for different jobs.
Getting Started with Cleanr
Start with Cleanr's free tier to clean up your photo using auto-enhance, object removal, or background replacement.

Frequently asked questions
Is HSL the same as saturation?
No. Saturation alone affects how intense all colours are. HSL saturation targets one colour range, leaving others untouched. HSL also includes hue (colour shift) and lightness (brightness of that colour only), giving three independent controls per colour family.
Can I use HSL adjustment on any photo?
Yes. HSL works on any photo, though it's most useful when you have distinct colour regions you want to adjust separately, such as portraits with skin and clothing, or landscapes with sky and foliage.
Do I need a subscription to use HSL in Cleanr?
Yes, HSL colour adjustment is part of the AI Pro tier (£12.99/mo or £99.99/yr). The free tier includes basic brightness, contrast, saturation, and warmth adjustments, but not colour-range-specific HSL control.
What other advanced colour tools does Cleanr offer?
AI Pro includes tone curves for pixel-level brightness adjustments across the tonal range, and selective adjust, which lets you mask a region with a brush and adjust brightness, contrast, or saturation just within that area.
Can I batch-apply HSL adjustments to multiple photos?
Yes. Cleanr's AI Pro tier supports batch processing of up to 50 photos. You can apply your HSL adjustments to one photo, then batch-export the same settings across dozens of images.
Is Cleanr good for product photography?
Yes. Small business owners use Cleanr to clean up product shots with object removal and background replacement, then fine-tune colours with HSL or curves. No watermark appears on free exports, and the AI Pro tier includes a commercial licence for Shopify, Etsy, or other storefronts.
