Communication

Color contrast is an important part of making digital content easy to read for everyone, including people with low vision or color blindness. Good contrast helps users clearly see text, links, and important information across websites, emails, and social media.

What Is Color Contrast?

Color contrast is the difference between the text color and the background color.

  • ✅ Black text on a white background (easy to read)

  • ❌ Light gray text on a white background (hard to read)

Required Contrast Ratio

All district content must meet a minimum contrast ratio of 4.5:1 for normal text.

This applies to:

  • Websites

  • Emails and newsletters

  • Social media graphics

  • Digital flyers and documents

  • Schoology and other digital platforms

Why It Matters

Low contrast can make content difficult or impossible to read for:

  • People with visual impairments

  • Users viewing content on mobile devices

  • Anyone in bright or low-light environments

Accessible contrast helps make sure everyone can read and understand your message.

Best Practices

  • Use dark text on a light background or light text on a dark background

  • Avoid light colors like yellow, light gray, or pastels on white backgrounds

  • Make sure links stand out clearly from the surrounding text

  • Use readable font sizes (at least 12–14pt for most content)

❌ Inaccessible Example

This text is too light and difficult to read on a white background.

✅ Accessible Example

This text has strong contrast and is easy to read.

Don’t Rely on Color Alone

Color should not be the only way you share information.

  • ❌ “Students in red are absent.”

  • ✅ “Absent students are marked in red and labeled ‘Absent’.”

Always include text labels or symbols so all users can understand the message.
