Satin Reader

Remap colors in a PDF. The default is a dark mode mapping white to dark grey and black to light grey, preserving hue and saturation.

Satin is a browser extension that allows you to map specific colors in a PDF file to other colors. The default settings toggle to a "dark mode" where white is changed to a dark grey and black is changed to a light grey instead of a direct high-contrast inversion most extensions offer. This also retains the original coloring for images and diagrams, unlike a full inversion.
