new feature color for text color

README.md

@@ -115,6 +115,7 @@ Layout options are set as options to the `\documentclass`, e.g.:
 - `bgscale=`: background image scale factor (1.0 = 100% of card height), default: `1.0`. Use values like `1.5` or `2.0` for zoomed/cropped backgrounds. Only affects images, not colors. Can be overridden locally with `\background[scale=...]{file}`.
 - `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.
