What High Contrast Mode does
High Contrast Mode applies a color filter over the page you're viewing to make text and elements easier to read. You choose between four modes: increased contrast, greyscale, inverted color, and inverted greyscale, and can switch between them or turn the effect off with the toolbar icon.
High Contrast Mode's four modes explained
Increased contrast boosts the difference between text and background without changing hues. Greyscale removes color entirely. Inverted color flips the page's color values, which many people use as a dark-mode-like effect on light sites. Inverted greyscale combines both for maximum contrast in black and white.
Is High Contrast Mode safe?
The developer states no user data is shared and the extension shows no ads. It needs to read and modify the content of pages you visit in order to apply the color filter, which is standard for any visual-adjustment extension.
