Sitehue: Website Customizer од Calvin Iyer

Sitehue gives you complete visual control over every website you visit, combining a universal default look with per-website overrides and strict site access rules.

Key features
- Typography control: choose custom body, heading, and monospace fonts, adjust text scale, line height, letter spacing, word spacing, and paragraph spacing for effortless reading across the web.
- Colors and backgrounds: restyle page backgrounds, elevated surfaces, body text, headings, links, borders, and text selection highlights, or apply curated themes like Warm Paper, Espresso Night, Solarized Calm, and High Contrast Ink.
- Visual filters and media: fine-tune page brightness, contrast, sepia warmth, grayscale, hue rotation, color inversion, and dim overly bright images or videos.
- Layout and reading comfort: constrain sprawling pages to a comfortable reading column, hide distracting page elements, force clear focus outlines, disable jarring animations, and add custom style rules.
- Granular per-website overrides: customize individual websites without losing your global defaults. Override only the settings you want on a particular domain while everything else inherits from your global profile.
- Mutually exclusive access lists: apply your styles everywhere except on websites in your Exclusion List, or only on websites in your Allowlist. Enabling one list clears and locks the other so your rules never conflict.
- Light and dark interface: warm light, espresso dark, and auto system themes for the Studio and popup.
- Real-time live preview: see styled pages side by side with your controls, or compare against global defaults.

How to use
1. Click the Sitehue icon in your toolbar to toggle styling on the current website, apply a one-click theme preset, or override specific settings for that domain.
2. Click "Studio" to configure your Global Customization Profile, manage Per-Website Overrides with a live side-by-side preview, and configure your Exclusion List or Allowlist.
3. Export or import your complete configuration as a backup file at any time.

Privacy and permissions
All of your customization profiles, site overrides, and domain lists are stored locally on your device. Sitehue is free and ad-free, and never collects, tracks, or transmits your browsing history or personal data. When you choose a Google Font for a page, your browser loads that font directly from Google Fonts.

Support
This extension is free and has no paid features. If you find it useful, you can optionally donate through GitHub Sponsors or Buy Me a Coffee using a link in the Studio settings page or the small "Support" link in the toolbar popup. Donating changes nothing in how the extension works.
