Web Content Accessibility: Color Contrast

The following table serves as a guide, as determined by the Web Content Accessibility Guidelines (WCAG) 2.0, for web color combinations that have a high enough contrast to be accessible to people with disabilities, including blindness and low vision. When using a background color for a section on the NSU website, this guide will help determine which text color can be used on top of it to meet accessibility standards.

Large text is defined as 14 point (typically 18.66px) and bold or larger, or 18 point (typically 24px) or larger.

A "Pass" indicator signifies that this color combination is a high enough contrast to be accessible as per the text size defined. A "Fail" indicator signifies that the color combination is not accessible and should not be used with the indicated text size.

NSU’s color palettes are designed to boldly enhance our visual elements. There is a primary color palette that you should use for most applications, and a secondary palette that should be used sparingly to complement the primary colors.

The palettes are available in the following formats:

  • RGB - for computer monitors and other electronic display screens
  • CMYK or Pantone™ - for print applications
  • HEX - for HTML and web-based use

Primary Colors

The university’s primary colors are NSU Blue (PMS 287C) and Main Gray (PMS 430C). Use these colors at 100 percent opacity whenever possible. NSU Blue should be present on all visual communication materials whenever possible.
