## Description

Midnight Lizard is a powerful Chrome extension that transforms your browsing experience with customizable color schemes across all websites. Choose from predefined options like night mode, dark themes, grayscale, or colorful palettes, or create your own tailored to your preferences. It offers features such as adjustable brightness, saturation, contrast, and hues to improve accessibility and readability. Enhance eye comfort with blue light filtering that shifts colors towards red light without inverting images.

The extension supports website-specific color schemes, scheduling for automatic activation, keyboard shortcuts for quick toggling, and syncing of your personalized settings. It's designed for flexibility, allowing global or per-website application with whitelist or blacklist modes, and optimizing performance with a simplified mode for heavy sites. Open source and community-supported, Midnight Lizard brings a rich set of tools to make web pages more comfortable and easier to read while protecting your eyes during extended screen time.

## Review summary

Midnight Lizard is generally useful for applying dark-mode styling and improving readability across sites, with positive views on its functionality. However, reviewers repeatedly cite customization limitations (no custom color schemes or import/export), lack of per-site toggles, potential performance slowdown, and confusing filter interactions. Despite these gaps, many users find it to be a solid tool for reducing eye strain and achieving consistent dark-mode across websites.

### Pros

- Improves readability by forcing dark-mode text on websites and enhancing eye comfort.
- Functional and generally well-regarded as a practical dark-mode extension.
- Gets the job done across many sites and is perceived as a solid overall tool for dark-mode needs.

### Cons

- Customization is limited: you cannot create or duplicate color schemes, and importing/exporting themes is not supported (only renaming predefined themes).
- No per-site toggle or quick on/off control is available, making site-by-site adjustments cumbersome.
- Can slow down pages, similar to other dark-mode extensions, impacting performance.
- Filter settings can be hard to predict or pinpoint in how they interact, leading to a confusing tuning experience.
