How to use Adjust Colors

  1. Add the image

    Drop in the photo you want to correct.

  2. Fix exposure first

    Get overall brightness right before touching anything else — every other adjustment depends on it.

  3. Then white balance, then saturation

    Neutralise any colour cast, then adjust saturation last and sparingly.

  4. Export

    Compare against the original one final time before saving.

When to use Adjust Colors

  • Correcting the orange cast from indoor tungsten lighting
  • Rescuing an underexposed photo shot against a bright window
  • Making product colours accurate for a listing
  • Matching the look of photos taken in different lighting conditions

FAQ

Six sliders: brightness, contrast, saturation, hue rotation, colour temperature and invert. There is no gamma control — brightness and contrast together cover most of what people reach for gamma to do.
Yes, either way round. Reset a single slider to its default, or reset all six at once.
Tungsten and warm LED lighting is much warmer than daylight, and automatic white balance often under-corrects. Adjust white balance cooler until something you know is white looks white.
Exposure, white balance, contrast, then saturation. Each step changes how the next one appears, so working out of order means redoing things.
Only partially. Areas that are pure white contain no data to recover. Underexposed photos are far more recoverable than overexposed ones, which is why erring dark is safer when shooting.
Screens vary widely in brightness and colour calibration. If colour accuracy matters, check on at least two devices and avoid making decisions on a screen set to maximum brightness.

About Adjust Colors

Colour correction follows a specific order for a good reason: each adjustment changes how the next one reads. Exposure first, because brightness affects perceived colour. White balance second, to remove any cast. Contrast next. Saturation last, and gently — it is the adjustment people most consistently overdo.

The most common fault in everyday photos is a colour cast from artificial light. Tungsten bulbs push everything orange, older fluorescents push green, and overcast daylight pushes blue. Cameras try to compensate automatically and frequently get it wrong, particularly under mixed lighting where there is no single correct answer.

A reliable technique: find something in the frame that should be neutral grey or white — a wall, a sheet of paper, a white shirt — and adjust until it actually looks neutral. Everything else in the image falls into place once the neutral is right, and it is far more dependable than adjusting by eye alone.

Tips and limits

  • Order matters: exposure, then white balance, then contrast, then saturation.
  • Find something that should be neutral grey or white and correct until it is.
  • Saturation is the most over-applied adjustment. Small changes go a long way.
  • Mixed lighting has no single correct white balance — pick the light on your subject.
  • Check the result on another screen if colour accuracy actually matters.
