What Are the Best Background Colors for Reading with Dyslexia?
• By Elliott Tong
Peach (#EDD1B0) produced the best reading performance in a 341-participant study by Rello & Bigham (2017). Warm backgrounds reduce visual stress, which affects up to 46% of dyslexic readers. The British Dyslexia Association recommends cream or soft pastels over white. Pure white overstimulates the visual cortex, causing words to blur, flicker, or appear to move.

White Backgrounds Are Probably Making Your Reading Harder
Most apps and websites default to pure white. Nobody questions it. But for a significant portion of readers, white is actively working against them.
The problem is visual stress. When black text sits on a bright white background, the high contrast creates a striped pattern that can overstimulate the visual cortex. For some people, that makes words blur, double, or appear to drift across the page.
How many people does this affect?
Visual stress (also called Meares-Irlen Syndrome or scotopic sensitivity) affects 12-14% of the general population. Among people with dyslexia, that number climbs to 46%. Nearly half.
Symptoms include words appearing to move or swim, letters blurring or doubling, difficulty tracking lines, headaches after reading, and needing to re-read the same passage repeatedly. Many people assume this is just "how reading feels" because they have no comparison.
The Rello & Bigham study
In 2017, researchers Luz Rello and Jeffrey Bigham tested 10 different background colors with 341 participants, including 89 people with dyslexia. They measured both reading speed and accuracy.
The results: warm background colors significantly improved reading performance. Peach performed best overall. Cool colors and white performed worst. The effect was measurable, not just subjective preference.
The British Dyslexia Association agrees
The BDA Style Guide says "white can appear too dazzling" and recommends cream or soft pastel backgrounds. They also recommend off-black text (dark brown, navy, charcoal) rather than pure black, to soften the contrast without sacrificing readability.
These aren't opinions. They're guidelines from the primary dyslexia advocacy organization in the UK, informed by decades of clinical observation.
Which Colors Actually Work?
Not all colors are equal. The Rello & Bigham study tested a range, and the results point to a clear pattern: warm colors outperform cool colors and white.
Peach (#EDD1B0): best performer
Peach produced the highest reading speed and accuracy scores in the study. It's a warm apricot tone, paired with dark brown text (#3D2B1F). If you're changing one thing about your reading setup, start here.
Cream (#FEF9E7): BDA recommended
The British Dyslexia Association specifically recommends cream. It's subtle enough for extended reading, warm enough to reduce visual stress. Paired with soft navy text (#2C3E50), it follows BDA guidelines precisely.
Sepia (#F4ECD8): the e-reader standard
Sepia is familiar from Kindle and most e-readers. Slightly more muted than peach, it also reduces blue light exposure during long sessions. Paired with warm brown text (#5D4E37).
Mint (#E8F8F5): cool alternative
Some readers prefer cooler tones. Mint is less saturated than white and provides a gentle alternative. Research favors warm colors, but personal comfort matters. Paired with dark teal text (#0E4D45).
Dark (#1A1A1A): for low-light reading
Dark mode wasn't in the Rello study, but dark backgrounds reduce overall eye strain in dim environments. Off-white text (#FFFFFF) on near-black eliminates the brightness problem entirely.
What Doesn't Work (Despite Common Belief)
Some popular "solutions" for reading difficulty don't hold up under controlled testing.
Blue light glasses won't fix reading difficulty
Blue light glasses reduce one wavelength of light. Visual stress is about contrast patterns, not wavelength. If words blur or move on a white background, filtering blue light doesn't change the underlying problem. Changing the background color does.
Dark mode isn't always better
Dark mode reduces brightness, which helps in dim rooms. But the Rello study tested warm-toned backgrounds against dark backgrounds in normal lighting. Warm backgrounds performed better. Dark mode is a lighting solution, not a reading solution.
Specialty dyslexia fonts are not a substitute for color
OpenDyslexic and similar fonts target letter-shape confusion. Visual stress is a separate phenomenon caused by contrast patterns, not character shapes. A dyslexia font on a white background still has the white background problem.
Color and font are independent axes. You can change both. See our guide on the best fonts for reading for the font research.
Color Works Better With the Right Font and Spacing
Background color is one piece of a three-part system. Font choice and spacing are the other two, and they all interact.
Font choice varies 35% per individual
The ACM TOCHI study (n=352) found reading speed varies up to 35% depending on which font you use. Same text, same person, different font. That effect is personal, not universal. You need enough fonts to find your optimum (industry standard: 7-14 options).
Letter spacing produces a 20% speed gain
Zorzi et al. (PNAS 2012, n=74) found that letter spacing alone improved reading speed by 20% for dyslexic readers. No font change needed. Piazzesi et al. (2020) showed letter and word spacing should move together for the full effect.
The complete setup
Warm background color (peach or cream), a font that works for your brain, and spacing adjusted beyond the WCAG minimum. Research supports all three independently. Together they compound.
What a Good Color System Looks Like
If you're evaluating any reading tool for dyslexia-friendly color support, here's what the research says to look for.
Research-backed presets, not a color picker
A general color picker gives infinite choices but no guidance. Research-backed presets (peach, cream, sepia at minimum) remove the guesswork. The Rello study tested 10 colors. Not all warm tones are equal.
Optimized text color for each background
Each background needs its own text color. The BDA recommends off-black text, not pure black. But the right shade of off-black depends on the background. Peach pairs with dark brown. Cream pairs with navy. Getting this wrong cancels the benefit.
WCAG AAA contrast on every preset
Reducing contrast extremes is the point. But contrast still needs to meet WCAG AAA (7:1 ratio minimum) for the text to remain sharp. Every preset should maintain this floor.
Instant preview and saved preferences
Switching colors should be immediate. You need to read a full paragraph to know if a color works for you. And your choice should persist across sessions without resetting.
Tips for Finding Your Best Color
Color preference has a personal component beyond the group-level research findings.
Start with peach or cream
These performed best in research. Read for at least 5-10 minutes on each to give your eyes time to adjust. First impressions can be misleading.
Watch for symptoms, not preferences
The question isn't "which looks nicer?" It's "do words blur less?" Pay attention to whether text stays stable, whether you can track lines without losing your place, whether you get fewer headaches.
Different contexts, different colors
Bright room? Warm presets. Evening reading? Dark mode. Your optimal color may change with lighting conditions. That's normal.
Give it three days
Your visual system adapts. A new background color may feel strange for the first session. Read on it for three days before deciding. The adjustment is real.
