What is a Color Overlay?

A color overlay adds a transparent colored layer on top of the entire webpage. It is like looking through a sheet of colored plastic or glass.

Many people find that a tinted overlay reduces the harsh contrast of black text on white backgrounds. This can make text appear calmer and easier to read.


Who is This For?

This feature is helpful for:

  • People with dyslexia who benefit from colored overlays
  • Anyone with Irlen Syndrome or visual stress
  • People who find bright white screens uncomfortable
  • Anyone who experiences eye strain or headaches when reading online
  • Students who need to read for long periods

Step 1: Open Helperbird

Click the Helperbird icon in your browser toolbar. It looks like a small owl and is usually in the top-right corner of your browser.

This will open the Helperbird menu.

The Helperbird popup with Helperbird switched on, showing the quick actions grid and the All Features button


Step 2: Open the All Features Section

Scroll down to the bottom of the Helperbird menu. You will see a section called All Features.

Click the arrow next to All Features to expand it and show all available features.

The All Features list in the Helperbird popup, showing every feature in alphabetical order


Step 3: Find Color Overlay

Look through the list of features until you see Color overlay.

It has a red icon with a layers symbol on it.

The All Features list scrolled to show the Color overlay row and its Open button


Step 4: Open Color Overlay

Click the Open button next to Color overlay to open it.

A panel will appear with the overlay toggle at the top and a Settings section below it.

The Color overlay panel open in the Helperbird popup, showing the Color overlay control


Step 5: Turn on Overlay

At the top of the panel, look for the Color overlay toggle.

Click the toggle switch to turn it on.

A colored tint will immediately appear over the entire webpage, and a green Active badge will show next to the feature in the list.

The Color overlay toggle switched on in the Helperbird popup


Step 6: Customize the Overlay

To adjust the overlay color and intensity, scroll down to the Settings section in the same panel.

Here you can choose different colors and adjust how strong the overlay appears.

Overlay Settings

In the Settings section, you can customize the following:

  • Color - Choose a color for the overlay from the color grid. Popular choices include yellow, blue, pink, and green. Different colors work better for different people, so try a few to find what is most comfortable for you.

  • Opacity - Adjust how strong the overlay is using the slider or the minus and plus buttons. A lower opacity makes the overlay more transparent, while a higher opacity makes the color more intense.

  • Blend mode - Control how the tint mixes with the page. It is on by default, which keeps text sharp under the color. Turn it off to see the exact color you picked on every page. Read the guide to Blend mode in the color overlay for when to use each setting.

The overlay's color and opacity are separate from the reading ruler settings, so you can adjust each one independently.

Tip: Many people with dyslexia or Irlen Syndrome find that certain specific colors work best for them. If you have worked with a specialist who recommended a particular overlay color, you can match it here. Try different colors and opacity levels to find what feels most comfortable for your eyes.

turned a 28-page reading assignme...

I have ADHD and yesterday Helperbird and the text-to-speech function (available in free version) turned a 28-page reading assignment from a two-day task to roughly two hours, maybe three at the absolute most. It helped tremendously! And I loved that the text-to-speech has such a fluid voice compared to a lot of others I've used! Honestly, the fact that this was created by someone who knows the struggles is something I love, because then it has neurodivergency in mind. I've tried too many things in the past that were created by neurotypical folk trying to be helpful to us and I do appreciate it, but it doesn't work as well because our brains work different. Highly recommend!
