Coloured Reading Rulers – Making Reading Easier by Adjusting the Background Colour

For many students, especially those with visual stress, dyslexia, or concentration difficulties, reading dense blocks of text can feel overwhelming. Letters appear to shimmer, words seem to merge, and the page becomes uncomfortable to focus on. One simple, low-cost tool that can make a big difference is the coloured reading ruler.

At Philip M Russell Ltd and Hemel Private Tuition, we use these rulers in lessons to help students who struggle to track text or maintain focus. The science behind them is straightforward — and the impact can be immediate.

How Coloured Reading Rulers Work

Reading rulers combine two aids in one:

• A tinted overlay, which reduces visual stress caused by high contrast between black text and white paper.

• A tracking window, which isolates a single line of text and prevents the eyes from jumping around the page.

Different students respond to different colours — blue, yellow, green, pink, grey — each tint changing how the brain processes contrast and sharpness.

Who Can Benefit?

Coloured reading rulers can help students who experience:

• Words that appear to move or blur

• Glare from bright white paper

• Difficulty tracking from one line to the next

• Fatigue after only a few minutes of reading

• Loss of place in long paragraphs

• Dyslexia-related visual discomfort

They are not a cure, but they are a useful support tool that removes barriers and builds confidence.

Why They Help

Research suggests that certain colour wavelengths can reduce overstimulation in the visual cortex. By lowering contrast and softening the page, reading becomes more comfortable and less tiring.
In practical terms, students read:

• Longer

• More fluently

• With fewer mistakes

• With greater confidence

And because rulers are thin, inexpensive, and portable, they can be used anywhere — school, home, or tutoring sessions.

How We Use Them in Tuition

At Hemel Private Tuition, we:

• Test a range of colours to see which students prefer

• Use rulers during reading-heavy subjects such as Biology, English, and long exam questions

• Encourage students to bring their preferred ruler to school

• Combine reading rulers with structured line breaks and accessible fonts when preparing worksheets

It’s a simple intervention that often produces instant, visible improvement.

The Takeaway

Coloured reading rulers are a small tool with a big impact. By adjusting the background colour and helping students focus on one line at a time, they turn reading from a struggle into something achievable and comfortable.

Sometimes the best educational tools are the simplest ones.
