Color inversion replaces each channel value with 255 minus that value — white becomes black, red becomes cyan, and so on. It's useful for creating negative-film effects, dark-mode artwork, or checking contrast in design mockups. For other effects, try Grayscale or Brightness & Contrast.

What this tool is used for

Producing a negative to check an image's tonal structure.
Inverting a scanned film negative to see the positive.
Making a dark-background diagram readable on a light page.
Checking how a design reads with tones reversed.
Producing an inverted variant for a dark theme.

Frequently Asked Questions

What does inverting actually do?: Each of the red, green and blue channels is replaced by 255 minus itself, pixel by pixel. Alpha is left alone, so transparency survives. White (255,255,255) becomes black, and mid-grey (128) stays almost exactly where it is.
Is inverting twice lossless?: Mathematically yes — 255 − (255 − v) is v — but only if you save as PNG. Export as JPEG and the lossy re-encode changes pixel values, so a second inversion returns something close to, but not identical to, the original.
Is this the same as a film negative?: No. Colour negative film carries an orange mask over the whole frame to correct for dye impurities, so simply inverting a scanned negative gives a heavy cyan-blue cast. Proper conversion removes the mask first and applies a per-channel curve.
Why does inverting a photo look wrong rather than just reversed?: Because sRGB values are gamma-encoded, not linear light. Inverting the encoded number is not the same as inverting the physical brightness, so midtones shift in a way that looks unnatural. It is the standard behaviour every editor implements, and it is why the result feels off.
What is it useful for?: Reading a scanned negative, making a light-background diagram usable on a dark slide, checking whether an image still reads with reversed polarity, and generating a quick high-contrast variant for accessibility testing.
Does inversion affect the alpha channel?: No, only the colour channels are inverted. Transparent regions stay transparent, which is what keeps a logo's cutout intact — inverting alpha as well would turn the background opaque and the subject invisible.
Why is inverting not a way to make a dark-mode icon?: Because it reverses hue as well as brightness — a blue logo comes back orange. For dark mode you want the lightness flipped and the hue kept, which is a filter or a separate asset, not an inversion.

Common errors and gotchas

Inverting a colour image expecting a dark-mode version, which produces hue-shifted colours rather than a theme.
Assuming inversion is reversible on a lossy image, since re-encoding adds artefacts each pass.
Inverting a photograph and reading the result as a colour-corrected negative, which needs more than inversion.
Losing transparency by inverting the alpha channel along with the colours.
Inverting a logo, which usually breaks brand colours rather than adapting them.
