Make Text Stand Out

Some websites have poor contrast. Light gray text on white backgrounds. Thin fonts that disappear. It's hard to read even with good vision.

High contrast mode fixes that. Apply a theme that makes text bold and clear against its background.

Learn how to enable high contrast mode

  • Color Overlay - Apply a colored tint to make reading more comfortable and reduce eye strain.
  • Color Blindness Support - Make links and interactive elements easier to identify.
  • Grayscale Mode - Remove distracting colors while maintaining strong contrast.

Available Themes

Inverted colors: Swap dark and light. A normal light page becomes light text on a dark background.

Yellow on black: High visibility combination, popular for low vision users.

Grayscale: Remove color distractions while keeping contrast.

Inverted grayscale: Dark background with light gray text.

Increased contrast: Boost the existing contrast without changing colors dramatically.


Why High Contrast Helps

Low vision: When text is hard to see, high contrast makes it readable.

Color blindness: Removing or simplifying colors can make content clearer.

Eye strain: Strong contrast means your eyes don't have to work as hard to distinguish text from background.

Poor website design: Some sites just have bad contrast. High contrast mode overrides their choices with something readable.


Who Uses This

People with low vision who need strong contrast to read.

Users with color blindness who benefit from simplified color schemes.

Anyone reading in bright light where low-contrast text washes out.

Night readers who want a dark theme across all sites.

More accessibility features

This is my first google review ever! I have to share that the accessibility and support for independent access for students that Helperbird provides, is a game changer. It is constantly being updated with new features based on feedback and it is extremely user friendly. The ability to customize the settings allows students to have control over their own learning, aligning with Universal Design for Learning. Looking forward to sharing with students and fellow educators on a daily basis. Thanks, Helperbird team!
