Does Midnight Lizard Improve Accessibility and Readability?

Updated

Midnight Lizard can improve accessibility and readability for many people, but it is a general-purpose visual adjustment tool rather than a certified accessibility solution. It works by applying custom color schemes to websites and letting you tune brightness, saturation, contrast, and hues, plus filter blue light and shade bright colors and images. If your difficulty is glare, low contrast, or color discomfort while reading on screen, it is likely to help. If you rely on a screen reader, need semantic page changes, or require WCAG conformance guarantees, it does not replace those tools.

What Midnight Lizard actually changes

The extension applies a color scheme on top of every website rather than waiting for site owners to add a dark mode. According to its own description, each scheme works across all sites and does not become outdated, and you can choose between dark, light, grayscale, or colorful schemes.

The adjustable controls are:

  • Brightness — overall lightness of the page
  • Saturation — how vivid or muted colors appear
  • Contrast — separation between text and background
  • Hues — shifting color tones across the page

It also offers a blue light filter for evening use and the ability to shade bright colors and images.

How each feature maps to a readability or accessibility need

Your problem Relevant feature What it does for you
Bright white pages cause glare Dark or light schemes, brightness Lowers overall luminance so the page is less harsh
Text blends into the background Contrast Increases separation between text and background
Vivid colors are distracting or painful Saturation, grayscale scheme Mutes or removes color so content is calmer to read
Specific hues are uncomfortable Hues Shifts color tones away from problematic ranges
Bright images or blocks are jarring Shade bright colors and images Dampens high-luminance areas
Evening screen use feels straining Blue light filter Reduces blue tones at night

Which reading and eye-comfort scenarios it suits

  • Long reading sessions on text-heavy sites — a dark or low-brightness scheme with raised contrast reduces sustained glare.
  • Evening or low-light use — the blue light filter plus a dark scheme targets the time of day when bright screens feel most straining.
  • Light sensitivity or glare discomfort — shading bright colors and images directly addresses high-luminance elements.
  • Color vision differences or color distraction — grayscale removes color as a variable entirely, while hue adjustment lets you shift tones.
  • Mixed browsing across many sites — because schemes apply everywhere, you do not depend on each site offering its own dark mode.

Where it does not help

  • It changes appearance, not page structure or semantics, so it does not fix missing alt text, poor heading order, or keyboard navigation.
  • It is not a substitute for a screen reader or other assistive technology.
  • It does not guarantee WCAG compliance for any site.
  • Aggressive contrast or hue settings can sometimes make specific sites harder to read, so per-site tuning may be needed.

A practical way to test whether it helps you

  1. Install the extension in Chrome or Firefox.
  2. Start with a dark scheme and lower brightness on a page you read often.
  3. Raise contrast until text separates cleanly from the background without looking harsh.
  4. If colors distract you, switch to grayscale or reduce saturation.
  5. If a particular hue bothers you, adjust hues rather than abandoning the scheme.
  6. For evening reading, enable the blue light filter.
  7. If bright images still glare, turn on shading for bright colors and images.

If reading feels easier after these steps, the tool is doing its job for your situation. If your difficulty is understanding or navigating content rather than seeing it, look to accessibility tools that change structure and semantics instead.
