brushup.el

Dynamic theme-aware color palette for Emacs.

Brushup generates gradient colors from your current theme's foreground and background, so face customizations work consistently across any theme. When you switch themes, all registered styles automatically update.

Features

• Parametric gradient generation from theme colors
• Automatic dark/light theme detection
• Style registration system for face customizations
• use-package :brushup keyword integration
• Re-evaluates all styles on theme change
