Audio: There's something about great design that allows it to go practically unnoticed.

Visual: Signs with directions are shown. A woman is walking happily down the street.

Audio: But it doesn't take much to make things confusing and frustrating.

Visual: The signs change to have poor contrast. The woman now looks confused.

Audio: Choosing colors with poor contrast makes navigating, reading and interacting a real pain

Visual: She looks at a navigation app on her phone.

Audio: Good design means sufficient contrast between foreground background and colors. That's not just text and images but links, icons, and buttons.

Visual: The app has a button with low contrast that changes to become clear.

Audio: If it's important enough to be seen, then it needs to be clear. And this is essential for people with low contrast sensitivity. Which becomes more common as we age.

Visual: An older man on a sofa is looking at a tablet. He goes to read a message on his mobile phone.

Audio: With good colors, websites and applications can be easier to use in more situations. Like in different lighting conditions.

Visual: Sun glares on the phone but the text is still readable.

Audio: Web accessibility: Essential for some, useful for all.
