KTBox is a modular LaTeX framework that introduces semantic color palettes, structured highlight boxes, and ORCID-linked author utilities for scholarly writing. The package is composed of three lightweight and independent style files: ktbox.sty – defines highlight boxes (standard, numbered, wide) with semantic theming. ktcolor.sty – provides semantic color palettes with light and dark modes. ktorcid.sty – adds ORCID-linked author commands and icons. The framework separates structure from style, ensuring compatibility with major classes such as IEEEtran, acmart, article, beamer, and ICLR. Features include numbered key-takeaway boxes, wide-format environments for emphasis, multi-column layouts, and dual light/dark themes. KTBox aims to improve clarity, portability, and reproducibility in academic publishing across articles, posters, and presentations.
