You learned what white balance is, how color temperature works and why correction comes before creative grading in the color course. This lesson is about the practical tools in your editing software: how to use the white balance picker and sliders, how to check whether a neutral is truly neutral using numbers, how to correct skin and individual colors, how to fix casts in only part of an image, and how to keep a whole set consistent.
Color correction in practice
Color correction in editing means removing unwanted casts and making colors look accurate and natural before any creative look. The principles were covered in white balance settings, RAW and white-balance flexibility and color correction versus creative color grading. Here the focus is on the tools.
White balance tools
| Tool | How to use it | Notes |
|---|---|---|
| White balance picker (eyedropper) | Click on something that should be neutral: a gray card, white wall, gray stone | Avoid bright clipped areas and colored surfaces |
| Temperature slider | Move toward blue or yellow (cool or warm) | Main correction for most casts |
| Tint slider | Move toward green or magenta | Fixes fluorescent and some LED casts |
| Presets | As Shot, Daylight, Cloudy, Tungsten and others | Quick starting points for RAW files |
Tip:Click several different neutral areas with the picker and compare. If results differ a lot, the scene may contain mixed lighting, as in mixed lighting.
Checking neutrals with numbers
Your eyes adapt to color casts, but numbers do not. Most editors show the RGB values under the cursor. In a neutral gray, white or black area, the red, green and blue values should be approximately equal.
| Reading (R, G, B) | Meaning | Correction |
|---|---|---|
| About equal, e.g. 128, 128, 128 | Neutral | None |
| Blue highest, e.g. 120, 125, 140 | Cool cast | Warm the temperature |
| Red highest, e.g. 145, 128, 115 | Warm cast | Cool the temperature |
| Green highest, e.g. 125, 140, 125 | Green cast | Move tint toward magenta |
Calibrate your monitor first, as in monitor calibration and consistent viewing, so visual judgments also match the numbers.
Correcting skin
After global white balance, skin is the most sensitive check. Common problems and solutions were covered in color correction versus creative color grading. In editing tools, the orange hue, saturation and luminance controls in the color mixer (HSL) are usually the most effective for fine skin adjustments, with small changes only.
Color mixer and targeted color tools
| Tool | What it does | Example use |
|---|---|---|
| Color mixer (HSL) | Changes hue, saturation and luminance of one color range | Make a sky deeper blue, calm a bright green |
| Targeted adjustment tool | Click and drag on a color in the image | Precise, visual adjustment |
| Color calibration (in some RAW editors) | Adjusts how the camera's primary colors are interpreted | Overall color character of a camera |
| Selective color (in some editors) | Adjusts the ink-like components of specific colors | Fine color refinements |
Local color correction
When different parts of an image have different casts, such as a warm lamp-lit face and a blue window background, global white balance cannot fix both. Use local adjustments with masks to correct each area separately, as covered in local and targeted adjustments.
Correcting sets consistently
- Correct one representative image per lighting situation.
- Sync or copy the white balance and color settings to similar images.
- Compare images side by side, especially skin and neutral areas.
- Adjust individual images where light changed.
This builds on RAW development workflow.
Common mistakes
- Clicking the picker on colored or clipped areas: new casts.
- Ignoring tint: green or magenta casts remain.
- Trusting tired eyes or an uncalibrated screen: check numbers.
- Big HSL changes on skin: unnatural, blotchy tones.
How professionals correct color
Professionals photograph a gray card or color target, use the picker on it, then check neutrals with RGB readouts on calibrated screens. They fine-tune skin with small HSL changes, correct mixed light locally and sync settings across sets. Only after correction do they apply any creative grade.
Practical examples
A cool indoor portrait
- Situation
- A white wall reads R 120, G 126, B 142.
- What to do
- You raise the temperature until the wall reads about 130, 130, 130.
- Why it works
- Equal RGB values indicate a neutral gray.
- Result
- Natural skin and a neutral white wall.
A green office scene
- Situation
- After correcting temperature, the image still looks slightly green.
- What to do
- You move the tint slider toward magenta while checking a gray area.
- Why it works
- Fluorescent casts need tint correction, not only temperature.
- Result
- Clean, neutral color.
Key points
- Use the white balance picker on true neutrals, then refine temperature and tint.
- In neutral areas, red, green and blue values should be about equal.
- Fine-tune skin with small changes to orange in the color mixer.
- Use HSL, targeted tools and calibration controls for specific colors.
- Correct mixed light locally and sync settings across sets.
