Frequently asked questions
How is color inversion calculated mathematically?
Every pixel channel is inverted using the formula (255 - Value). Pure white (255, 255, 255) becomes pure black (0, 0, 0), and blue becomes yellow.
Does inverting an image invert the transparent background?
No. The alpha channel remains completely untouched, so transparent PNGs and logos retain their transparent borders.
Is color inversion useful for reading scanned documents?
Yes! Inverting black text on white paper produces white text on a black background, creating an eye-friendly dark mode for night reading.
