Hue is the name of a color: red, orange, yellow, green, blue, purple. Saturation is how strong or pure that color is, from a vivid, full color down to a neutral gray with no color at all. To change saturation in a photo, use a saturation slider in your editor: drag it right to make colors stronger, left to weaken them, and all the way left to remove color completely.
Hue, saturation and lightness (or brightness) are the three properties that describe any color you see in a photograph. Every color editing tool, from a phone app to Photoshop, is built around changing one or more of them. Learn what each one does and you can fix a dull image, calm a garish one, change one color without touching the rest, or tint a whole photo.
Hue, saturation and lightness defined
Most editing software describes color with a model called HSL (hue, saturation, lightness) or HSB (hue, saturation, brightness). The three properties are independent, which is what makes the model so useful: you can change one without changing the other two.
- Hue is the position of a color on the color wheel. It is measured in degrees around the circle: red sits at 0 degrees, green at 120 and blue at 240, with yellow, cyan and magenta between them. Changing hue swaps one color for another, so a red car can become orange or purple.
- Saturation is the intensity, purity or strength of a color. A fully saturated color contains no gray. As you lower saturation the color mixes with more gray until, at zero, only a neutral tone remains. That is why setting saturation to its minimum turns a photo black and white.
- Lightness or brightness is how light or dark the color is. Raising it pushes the color toward white, lowering it pushes the color toward black. Strongly lightened or darkened colors also look less saturated, because they move toward white or black.
A useful way to keep them apart: hue answers “which color?”, saturation answers “how much color?”, and lightness answers “how bright?”. The wider subject of how color works in a picture, including warm and cool palettes and color harmony, is covered in color in photography.
What hue means in photography
In photography, hue refers to the actual colors in the scene and how the camera and the editor render them. Two things decide the hues in a finished photo. The first is the light: the color temperature of sunlight, shade, tungsten bulbs or LEDs shifts every hue in the frame warmer or cooler. The second is processing: white balance, camera color profiles and any edits you make.
When an editor offers a hue control for one color range, it lets you nudge that range around the color wheel. Shifting greens slightly toward yellow makes foliage look warmer and more autumnal; shifting them toward cyan makes it cooler. Shifting oranges a little toward red or yellow is a common way to correct skin tones. Small hue moves of a few degrees are usually all a photo needs.
If every color in an image looks wrong in the same direction, for example everything has a blue or green tint, the problem is a color cast, and the fix is white balance, not hue sliders.
What saturation means in photography
Saturation describes how colorful a photograph looks overall and how intense each individual color is. A sunset with deep orange and magenta clouds is highly saturated; a foggy morning in soft gray-blue tones has low saturation. Neither is better. Saturation is a creative choice that changes the mood of a picture: high saturation reads as bold, energetic and cheerful, low saturation as calm, nostalgic, somber or gritty.
Several things affect saturation before you ever edit:
- Light quality. Soft, even light and the warm, low light near sunrise and sunset tend to show rich color. Harsh midday sun creates glare and bright reflections that wash colors out.
- Exposure. Overexposed areas lose color as they move toward white, and clipped highlights have no color left to recover. Slight underexposure often looks more saturated.
- A polarizing filter. It cuts reflections from leaves, water and the sky, which reveals the color underneath and deepens blue skies.
- Camera settings. The camera’s picture style or color profile includes a saturation setting. It is applied to JPEG files. Raw files store the sensor data without it, and you choose the color treatment later in the editor. See raw vs JPEG for what else differs.
Not sure whether to reach for vibrance or saturation? Vibrance vs saturation compares the two sliders side by side and shows when each one is the right tool.
How to change saturation
Every editor has a global saturation control. The steps are the same idea everywhere: open the color or adjust panel, find the slider, and move it while watching the image.
- Lightroom and similar raw editors: the main editing panel has Saturation and Vibrance sliders, each running from -100 to +100. Zero is the unchanged image and -100 on Saturation removes all color.
- Photoshop: add a Hue/Saturation adjustment layer (Layer > New Adjustment Layer > Hue/Saturation) and drag the Saturation slider. It also runs from -100 to +100.
- Phone editing apps: look for a slider labeled Saturation, Color or Vibrance in the adjust or edit tools.
Vibrance first, saturation second
Most raw editors offer vibrance as well as saturation. Saturation raises every color by the same amount, so colors that are already strong quickly become harsh and lose detail. Vibrance is a smarter version: it raises muted colors more than colors that are already intense, and it tends to protect skin tones from turning orange. For a general boost, try vibrance first and add only a little saturation if the photo still needs it.
How much is too much
Saturation is one of the easiest edits to overdo. A slider that looks right after staring at a photo for five minutes often looks garish the next day. Watch for these signs that you have gone too far:
- Skin looks orange, red or sunburned.
- Blue skies turn an electric, unnatural blue or show banding.
- Bright colors lose their texture and become flat blobs, for example the petals of a red flower.
- Grass and leaves look neon green.
A good habit is to push the slider until it is clearly too much, then pull it back to roughly half of that. Check the photo again later with fresh eyes. If you want an exaggerated, surreal look, that is a valid choice; just make it on purpose.
Changing one color at a time
Global sliders change every color together. Often the better edit is to change one color range and leave the rest alone: calm a distracting red sign, deepen the blue of the sky, or desaturate a busy green background behind a portrait.
In Lightroom: the color mixer
Lightroom’s HSL panel (called the Color Mixer in newer versions) splits the image into eight color ranges: red, orange, yellow, green, aqua, blue, purple and magenta. Each range has its own Hue, Saturation and Luminance slider, so you can, for example, lower the saturation of greens and shift their hue toward yellow without affecting the sky. The targeted adjustment tool lets you click on a color in the photo and drag up or down; the software works out which sliders control that color and moves them for you.
In Photoshop: the Hue/Saturation dialog
The Hue/Saturation adjustment has a dropdown at the top that starts on Master, which affects every color. Change it to Reds, Yellows, Greens, Cyans, Blues or Magentas to work on one range only. The color bars at the bottom of the panel show which range is selected, and you can drag the small sliders between them to widen or narrow it. The hand icon works like Lightroom’s targeted tool: click a color in the photo to select its range, then drag left or right to change its saturation, or hold Ctrl (Windows) or Cmd (Mac) while dragging to change its hue.
Replacing a color
To turn a red jacket blue or a green door yellow, select the color range for that object in Hue/Saturation and move the Hue slider until the new color appears. If the same color appears elsewhere in the frame, paint black on the adjustment layer’s mask over every area that should stay unchanged, so the edit only shows on the object. Photoshop also has a Replace Color command (Image > Adjustments > Replace Color) that selects a color with an eyedropper and a Fuzziness slider, then changes its hue, saturation and lightness. It edits the pixels directly, so work on a duplicate layer.
Replacing a color works best when the object is clearly different in color from its surroundings and has visible texture or shading. Very dark, very light or nearly gray objects carry too little color to shift convincingly; for those, a new color painted on a layer set to the Color blend mode usually works better. Masks are explained in layers and masks in Photoshop.
A worked example: lowering saturation
Lowering saturation is as useful as raising it. A slightly desaturated photo can feel quieter and more timeless, and it keeps attention on shape, light and composition. The landscape below starts with strong, vivid color. Notice also the winding S curve of the river, which works as a leading line into the frame.
In this version, saturation was lowered with a Hue/Saturation adjustment, with the hue and lightness also pulled down slightly. The scene now looks muted and moodier.
Colorize: tinting a whole photo
The Hue/Saturation adjustment in Photoshop has a Colorize checkbox. Turning it on replaces every color in the image with a single hue, while keeping the original light and dark tones. The Hue slider then picks the tint and the Saturation slider sets how strong it is. A low-saturation brown gives a sepia look; a stronger color gives a bold, surreal wash.
For subtler effects, such as warm highlights and cool shadows, use split toning or the broader tools described in color grading. To remove color altogether and control how each color converts to gray, see black and white photography.

Work non-destructively
Raw editors such as Lightroom never change the original file, so you can always reset a slider. In Photoshop, the menu command Image > Adjustments > Hue/Saturation (shortcut Ctrl+U on Windows, Cmd+U on Mac) changes the pixels permanently. An adjustment layer does the same job but stays editable: you can reopen it, change the values, lower its opacity or mask it at any time. Use adjustment layers by default.
Also make sure the screen you edit on shows color accurately. A monitor that is too blue or too saturated will lead you to make the wrong corrections. Color management explains calibration and color profiles.
Common mistakes with hue and saturation
- Using saturation to fix a color cast. If everything is too blue or too yellow, correct white balance first. Saturation only makes the cast stronger.
- Boosting global saturation when one color is the problem. Target the color range instead.
- Ignoring skin. Skin sits in the red, orange and yellow ranges. Global saturation and changes to those ranges affect faces first.
- Judging the edit too soon. Your eyes adapt to strong color quickly. Toggle the adjustment off and on to compare, and look again later.
- Editing pixels directly. Destructive edits cannot be refined later. Use adjustment layers or a raw editor.
Try this: one photo, three moods
Pick a colorful photo and make three versions in ten minutes. First, raise vibrance until the colors feel rich but natural. Second, lower saturation by about a third for a quiet, muted look. Third, choose one color range, such as the greens or blues, and change only its hue and saturation while leaving everything else alone. Put the three side by side and decide which suits the subject best, and why.
Hue and saturation FAQ
What is hue in photography?
Hue is the color itself, such as red, yellow or blue, described by its position on the color wheel. In editing, a hue control shifts a color toward its neighbors, for example green toward yellow. It is one of the three properties of color, along with saturation and lightness.
What is saturation in photography?
Saturation is the intensity or purity of the colors in a photo. High saturation means vivid, strong color; low saturation means muted color; zero saturation means black and white.
How do I change saturation in a photo?
Open the photo in any editor and move the Saturation slider: right to strengthen colors, left to weaken them. In Lightroom it is in the main editing panel next to Vibrance; in Photoshop, use a Hue/Saturation adjustment layer. To change only one color, use the color mixer or the Hue/Saturation color range dropdown.
What is the difference between hue and saturation?
Hue is which color something is; saturation is how much of that color there is. Changing hue turns a red into an orange, while changing saturation turns a bright red into a dull, grayish red without changing which color it is.
Is it better to increase vibrance or saturation?
For most photos, vibrance is the safer first choice because it boosts muted colors more than strong ones and tends to protect skin tones. Saturation raises every color equally and is easier to overdo.
