Midnight Lizard

Custom color schemes for all websites: night mode, dark themes, blue light filter, screen shader, high contrast, grayscale, etc.

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.

User reviews

Midnight Lizard is appreciated for its functional color customization that helps users read more comfortably and customize text/link colors per site without CSS. However, users are frustrated by the lack of true color scheme creation, performance slowdowns similar to Dark Reader, and problems with YouTube overlays. The add-on also lacks a simple per-site toggle and suffers from glitches, indicating it needs updates for better usability and stability.
Pros
  • Effective color customization for easier reading, especially for users sensitive to bright backgrounds.
  • Functional and useful for customizing text and link colors on individual websites without needing CSS.
  • Works on the add-on store and generally performs its intended function.
  • One of the few add-ons that offers extensive color scheme customization.
Cons
  • Lack of ability to create or customize color schemes freely; relies on a poorly designed color scheme generator.
  • Performance issues such as slowing down websites, similar to Dark Reader.
  • Problems specifically with YouTube: text overlays are hard to read regardless of filter settings, making usage frustrating.
  • No simple per-site toggle or quick on/off switch in the panel icon, which reduces ease of use.
  • Frequent glitches and needs updates, especially concerning compatibility with YouTube.

doesn't let you create your own color schemes instead uses some bullsht "color scheme generator" which is badly designed. to the reply: hmm I wonder why people wanted simple colors? is it maybe because THERE IS NO WAY TO INPUT A COLOR YOU ACTUALLY WANT AND YOU JUST HAVE TO EYEBALL IT

I can't read white text on a black background without my eyes hurting a lot so this has been AMAZING.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Midnight Lizard requires a lot of sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • Critical ******* ****** ** *** ********* ******** ********************
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Midnight Lizard has earned a fairly good reputation and likely can be trusted.
