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.stydefines 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.
