Your brush is painting the red jacket AND the skin. Color Range Mask fixes that instantly — restricting any adjustment to only the colors you sample.
🧥Color Range is a secondary filter on any existing mask — not a mask itself. It tells Lightroom which colors within the masked area should actually be affected.
Core Concept
A Filter Inside Your Mask
🖌️
Brush Alone
Affects everything you painted — all colors, all tones. Color bleed onto adjacent areas is common.
🎯
Brush + Color Range
Affects only the pixels within the brushed area that match your sampled colors. Paint loosely — Color Range handles the precision.
💡Two layers: The primary mask (brush/gradient/AI) defines where. Color Range defines which colors within that area. Both work together.
Navigation
Where to Find Color Range
1
Create any mask in the Masking panel (press M)
Brush, gradient, Select Subject — any active mask works. Make sure it's selected in the Masks panel list.
2
Scroll down past the adjustment sliders — find "Range Mask"
The Range Mask dropdown is set to "None" by default. It's below the Sharpness and Noise sliders — easy to miss.
3
Click the dropdown and choose "Color"
The panel expands showing the Color Range eyedropper, color swatches, Amount slider, and Smoothness slider. Eyedropper is active by default.
👁️Watch the mask overlay update in real time as you sample colors. Press O to cycle overlay colors if red is hard to see on your subject.
The Eyedropper
Click vs. Click + Drag
👆
Single Click
Samples the exact pixel color under the cursor. Good for flat, uniform colors. May miss texture or tonal variation in the subject.
⬛
Click + Drag Rectangle
Samples every color inside the drawn rectangle. Captures highlights, shadows, and texture variations in one move. Better for real-world subjects.
✅For clothing, foliage, or any textured subject — always drag a rectangle rather than clicking a single pixel. Real-world colors are never perfectly flat.
Multiple Samples
Shift+Click to Add Colors
After placing your first sample, hold Shift and click (or Shift+drag) anywhere on the photo to add a second color to the selection. Up to five samples total.
1
First click / drag — samples the main color range
Drag across the mid-tone section of the subject for a balanced first sample that captures neither the brightest highlight nor the deepest shadow.
2
Shift+click the highlight area — adds bright tones to the selection
If the bright parts of your subject look patchy in the overlay, Shift+click there to add those lighter tones.
3
Shift+click shadow creases if needed
Deep shadow areas can shift hue enough to be missed by the first sample. Shift+click them to include. Watch the overlay — coverage holes are your guide.
⚠️A plain click (without Shift) replaces all existing samples and starts over. Press Cmd+Z / Ctrl+Z to undo accidental resets.
Key Control
The Amount Slider
Controls how strictly the pixel's color must match the sample. Low = exact match only. High = accepts a broad range of related colors.
Low
Amount 10–25 — Very tight match
Only pixels almost identical to the sample are included. May leave gaps in the subject. Use when adjacent colors are very similar to the target.
Mid
Amount 40–60 — Good starting point
Covers most of the subject while still excluding clearly different adjacent colors. Start here and adjust from both directions.
High
Amount 70–100 — Broad, loose match
Includes many related colors. Risk of bleeding into unwanted adjacent areas. Use only when the target color is highly distinct from everything nearby.
🎯Drag the Amount slider while watching the overlay. Find the highest value that still excludes the colors you want to protect.
Practical Use
Targeting a Red Subject
Complete workflow for boosting a red jacket without affecting nearby skin tones.
1
Brush mask — paint loosely over the whole subject area
Large, feathered brush. Paint broadly — don't try for precision. Include the face. Color Range will handle the color discrimination.
2
Range Mask → Color — drag across the jacket fabric
Drag a rectangle across a mid-section of the jacket. The overlay collapses instantly from the full brushed area to only the red jacket.
3
Adjust Amount — then push Vibrance up
Tune Amount until skin drops out of the selection. Then boost Vibrance or Saturation. Effect applies to the jacket only. Press \ to compare before/after.
⚡You can paint as loosely as you want with the brush. Color Range does the precision work automatically — separating the jacket from the skin by hue.
Practical Use
Pop Foliage Within a Gradient
A Linear Gradient + Color Range lets you enhance foreground foliage without the boost bleeding into the sky above.
🌿
Foliage — Sampled
Green and yellow tones get the Clarity + Saturation boost. Drag across leaves to capture the full foliage color range.
☁️
Sky — Auto-excluded
Blue sky is excluded automatically — it's a different hue. No additional masking needed. Clouds stay natural.
🌅Works with Linear Gradients, Radial Gradients, and Brush masks. Use Shift+click to add autumn yellows/oranges if the foliage has warm tones too.
Decision Guide
Color Range vs. Luminance Range
🎨
Color Range — Use When…
✅ Target has a distinct hue
✅ Adjacent elements: similar tone, different color
✅ Clothing, foliage, flowers, sky
✅ You can describe it by color name
☀️
Luminance Range — Use When…
✅ Target is defined by brightness
✅ Bright sky vs. dark foreground
✅ Adjusting only shadows or highlights
✅ You'd describe it as "the bright areas"
🏆Quick rule: color name = Color Range (red jacket, blue sky). Brightness description = Luminance Range (bright areas, shadows). Each mask can use one or the other — not both simultaneously.
Common Mistake
Mask Still Bleeding?
When Color Range still picks up areas you wanted to protect, work through these fixes in order.
Fix 1
Reduce the Amount slider
Drag Amount lower while watching the overlay. The selection tightens. Stop when unwanted areas drop out. The subject may lose edge coverage — that's the expected tradeoff.
Fix 2
Resample with a smaller, more targeted rectangle
Click without Shift to reset, then drag a small rectangle in the most color-pure area of the subject — away from edges where colors blend.
Fix 3
Shrink the primary brush mask area
Color Range only works within the brush or gradient mask. If the primary mask covers too wide an area, tighten it first — Color Range has less to discriminate against.
🔁The iterative approach: sample → adjust Amount → Shift+click if needed → adjust Amount again. A back-and-forth process gives the best results.
Advanced Technique
Select Subject + Color Range
AI masking gives you precision edges. Color Range gives you color specificity. Together they isolate a single garment in seconds.
1
Masking → Select Subject
AI masks the entire person precisely — face, hair, clothing, all included. Complex edges like hair are handled automatically.
2
Range Mask → Color inside the Select Subject mask
Scroll down in the mask's settings. The Subject boundary is now the region Color Range will work within.
3
Sample the garment color — watch the mask collapse to only that item
Drag across the shirt or jacket. Skin, hair, and other clothing are automatically excluded while staying within the Subject boundary.
🤖This combination is one of the most powerful and underused workflows in Lightroom. Entire clothing item masked and color-refined in under 30 seconds.
Your Challenge
🌤️
Color Range Challenge
Find a landscape with a blue sky and clouds. Complete each step.
🖌️ Create a Brush mask — paint broadly over the entire sky including clouds
🎨 Add Range Mask → Color — drag across the blue area of the sky
🎚️ Adjust Amount until the white clouds drop out of the selection
✨ Push Vibrance +30 and Saturation +15 — blue sky pops, clouds stay natural
🔀 Shift+click different parts of the sky if coverage is patchy

Lesson Recap + Up Next
1
Filter, Not a Mask
Color Range is a secondary refinement — it works inside an existing mask to restrict the effect to sampled colors only.
2
Drag + Amount
Drag a rectangle to sample. Shift+click to add. Tune Amount while watching the overlay — highest value that still excludes unwanted colors.
3
AI + Color Range
Select Subject gives AI-precision edges. Color Range gives color specificity. Together: any garment or colored element isolated in seconds.

Add brush strokes to an AI selection. Subtract areas from a gradient. Intersect two masks for surgical precision. Lesson 24 covers the composite masking system that turns individual masks into something far more powerful.
