The Claims

There are a few major claims that back dark mode’s superiority:

1. Reduced blue light can improve your circadian rhythm
2. Reduced brightness can minimize digital eye strain
3. Darker colour palettes can minimize battery usage on certain devices
4. Light-on-Dark text is more readable than Dark-on-Light text

We want to test that fourth claim and we need your help to do it!

Below, you’ll find 3 tests in dark mode and light mode. Their purpose is to test different factors that can impact the readability between display modes.

Complete the tests and submit your results with the form on the bottom of the page. The results will be used in an upcoming video by Answer in Progress.

Processing Speed Test

This is a modified Stroop test which can be used to measure a person’s processing speed. The goal is to submit the colour of the word.

Do one mode at a time. It does not matter which one you start with.

The countdown begins when you select the input box and start typing. You can submit your entry by hitting the space key or the enter key.

Proofreading Test

This is a typing test designed to measure the accuracy with which you read and respond to a random word.

Do one mode at a time. It does not matter which one you start with.

The countdown begins when you select the input box and start typing. You can submit your entry by hitting the space key or the enter key.

Legibility Test

This legibility test is inspired by the Snellen eye chart and is designed to measure how well you’re able to see characters of different sizes.

Do one mode at a time. It does not matter which one you start with.

The countdown begins when you select the input box and start typing. You can submit your entry by hitting the space key or the enter key.

The character sizes are randomly generated so it may load very small but try your best!
