The short answer
There is no universal best background colour for dyslexia. Cream or a soft pastel can be a sensible starting point, but the most comfortable choice varies from one person to another. The colour must also keep enough contrast with the text.
The British Dyslexia Association recommends dark text on a light background that is not stark white, while stressing that colour preference is individual. That is useful guidance, not a rule that cream, blue or yellow will improve everybody's reading.
If you want a quick starting set, test these five backgrounds with very dark grey text:
| Background | Example colour | Why test it | Watch for |
|---|---|---|---|
| Soft cream | #FFF4E5 | Reduces the glare some readers report from bright white | Can look yellow under warm lighting |
| Pale blue | #EAF4FF | A commonly requested cool-toned alternative | Very light text will lose contrast |
| Pale yellow | #FFF9D9 | A warmer option that some readers prefer | Strong yellow can become distracting |
| Pale grey | #F3F4F6 | Neutral and less bright than white | Mid-grey text may be too faint |
| White | #FFFFFF | A useful control for your comparison | Lower screen brightness before rejecting it |
These hex values are starting points rather than clinically validated prescriptions.
A 10-minute way to find your colour
Change only the background colour during the first test. If you change the font, spacing and brightness at the same time, you will not know which setting helped.
- Choose a passage of about 150 to 200 words that is new to you.
- Use the same font, text size, line spacing, screen and room lighting each time.
- Read it on white, cream, pale blue, pale yellow and pale grey backgrounds.
- After each version, score comfort, line tracking and visual disturbance from 1 to 5.
- Keep your two most comfortable colours and test them again on another day.
- Check that links, buttons and smaller text remain easy to distinguish.
Do not choose solely by reading speed from a single short attempt. Familiarity, tiredness and the difficulty of the passage can all affect the result.
Background colour and visual stress are not the same as dyslexia
Some people experience glare, movement, blur, headaches or discomfort when reading. These symptoms can have more than one cause. The British Dyslexia Association says that treating visual difficulty is not a treatment for dyslexia, although a coloured overlay may make reading more comfortable for some people.
If text appears to move, double or blur, or if reading regularly causes headaches or eye pain, arrange an eye examination with a registered optometrist. A browser overlay should not replace an eye check or a professional assessment.
Keep contrast strong enough
A comfortable tint still needs readable contrast. Dark charcoal text on a very light background is usually a safer starting combination than coloured text on a strongly coloured background.
Useful rules of thumb:
- avoid patterned or photographic backgrounds behind body text;
- avoid pure red and green combinations, which can create extra barriers for colour-blind readers;
- do not use low-contrast grey text just because it looks softer;
- test the setting in daylight and artificial light;
- keep headings, links and focus indicators visually distinct.
The Web Content Accessibility Guidelines set measurable contrast requirements for web content. Your preferred overlay should not make important controls or words disappear.
How to change a website's background colour
Some reading apps and websites offer themes, but many pages do not. Dyslexly's free browser extension lets you apply a colour overlay while you browse, then combine it with font, spacing, line focus and read-aloud controls if you want to test those separately.
A practical setup order is:
- set screen brightness to a comfortable level;
- choose a light background and dark text;
- increase text size if the words still feel cramped;
- adjust line height and word spacing;
- add line focus only if tracking across lines is difficult.
Save the combination that works for you rather than copying somebody else's settings. For a complete walkthrough, see how to customise text for dyslexia.
Printed pages, school and work
For printed material, try a reusable transparent overlay before asking for large amounts of coloured paper. It is cheaper to compare several shades and easier to see whether the preference remains stable.
At school or work, a useful request is specific and reversible:
I read more comfortably with dark text on a pale cream background. Could digital documents use that setting where practical, or could I use my own reading overlay?
The best adjustment is the one the reader has tested. Avoid describing one background as the official colour for dyslexia.
What the evidence supports
Evidence does not support ranking one tint as best for all dyslexic people. Current practical guidance supports personalisation, good contrast and reducing visual clutter. It also distinguishes reading comfort from diagnosing or treating dyslexia.
That means a careful conclusion is: test colour as one accessibility preference, keep the rest of the page readable, and retain it only if it makes reading more comfortable for you.

Frequently Asked Questions
Is cream the best background colour for dyslexia? Cream is a useful starting option because it is less stark than white, but it is not best for everyone. Compare it with other light backgrounds while keeping the text and lighting unchanged.
Is blue or yellow better for dyslexia? Neither colour is universally better. Some readers prefer a pale blue, others a pale yellow or neutral grey. The shade should be light enough to maintain strong contrast with dark text.
Can a coloured overlay diagnose dyslexia or Irlen syndrome? No. Finding a colour comfortable does not diagnose dyslexia or another condition. Seek an appropriate professional assessment if you have persistent reading or visual symptoms.
Should I use black text on a coloured background? Black or very dark grey text on a very light background is a sensible starting point. Check that smaller text, links and buttons still have enough contrast after applying an overlay.
