Scan the slide, then use your editing app’s colour balance tool to push the faded colour back the opposite way — reducing green with a magenta shift, or reducing pink/magenta with a green shift — until skin tones and known colours look natural again.
What you need
- A scanned copy of the faded slide
- Photoshop Elements, or another editor with a colour balance or hue tool
- 10 to 20 minutes
How slide film fades
Different slide film types fade in different, fairly predictable directions as their dye layers age — some shift green, others shift toward magenta or pink. There is no single fix that works for every slide, so this is a visual, trial-and-adjustment process rather than one exact setting.
How to correct the colour cast
- Open the scanned slide in your editing app and identify the direction of the cast — does the whole image look greenish, or pink/magenta?
- In Photoshop Elements, go to Enhance, then Adjust Color, then Color Variations, which shows you side-by-side previews of shifting the image in different colour directions.
- If the cast is green, click the preview that adds magenta (Elements labels this clearly); if the cast is pink or magenta, click the one that adds green instead.
- Apply small adjustments repeatedly rather than one large jump, checking the preview each time — Color Variations is designed to be clicked several times until it looks right.
- Once the overall cast is roughly corrected, use Enhance, then Adjust Color, then Adjust Color for Skin Tone if there are people in the photo, clicking on skin to fine-tune further.
- Check brightness and contrast too — faded slides often look flat as well as colour-shifted, so a small contrast boost can help after the colour is fixed.
Check the colours look plausible
Look at anything in the photo that should be a known colour — sky should look sky-blue, not green-blue; skin should look like skin, not pink-grey. If you have another slide or photo from the same roll or trip that is less faded, use it as a colour reference.
If the cast is hard to shift
If Color Variations does not have a strong enough effect, Elements’ Hue/Saturation tool (Enhance, then Adjust Color, then Adjust Hue/Saturation) gives more control over individual colour channels for a more severe cast. Some fading is uneven across the frame — if part of the slide is more faded than the rest, a single overall correction may not fix it perfectly everywhere, and that is a normal limitation of a badly faded original.
Next step
Restore faded colour in a 1970s print covers a related but different kind of colour fading, in printed photos rather than projected slides.
