 - `bgopacity=`: background image opacity/transparency (1.0 = 100% visible, 0.0 = invisible), default: `1.0`. Use lower values like `0.2` or `0.3` to fade the background so text remains readable. Only affects images, not colors. Can be overridden locally with `\background[opacity=...]{file}`.
 - `qrbgopacity=`: QR code background opacity (1.0 = solid white, 0.0 = transparent), default: `1.0`. White background behind QR code ensures scannability over background images. Use `0.0` for no background or lower values like `0.8` for semi-transparent. Can be overridden locally with `\qrlogo[opacity=...]{file}`.
 - `color=`: global text color for the entire document, default: `black`. Accepts any color name understood by `xcolor` (including mixes such as `blue!60!black`). Useful when printing on darker backgrounds to ensure legibility without redefining every style manually.
+- `qrcolor=`: QR module color, default: `black`. Set this (e.g., `qrcolor=darkred`) to recolor the QR code independently from the main text color while keeping sufficient contrast with the background.
