Seeing Clearly: Why Colour Contrast Matters More Than You Think

Listen to this article on audio below:

For people living with a visual impairment the way colours interact can make the difference between information or objects that are instantly readable and information or objects that are effectively invisible.

Good colour contrast isn’t just vital for reading — it also plays a crucial role in helping people with sight loss identify objects and navigate spaces safely. In the home, strong contrast between items and their surroundings makes everyday tasks easier: for example, using brightly coloured chopping boards against dark countertops, or choosing contrasting handrails, light switches, and door frames so they stand out clearly. When out and about, high‑contrast features such as yellow edges on steps, bold tactile paving, or brightly coloured bollards help obstacles become more visible, reducing the risk of trips, bumps, and collisions.

Examples of Strong Colour Contrast

Black Text on White

This classic pairing provides one of the highest contrast ratios available. It’s used everywhere from books to documents because it delivers clean, reliable readability.

White Text on Dark Blue

A softer alternative to stark black‑and‑white, this combination still offers excellent clarity, often used in digital interfaces and signage.

Yellow Text on Black

Bold, striking, and highly visible, this combination is particularly common in warning signs and high‑attention environments.

Dark Blue Text on Light Yellow

A comfortable, low‑glare pairing that some readers prefer over pure white backgrounds. It provides outstanding contrast while being easier on sensitive eyes.
