About

Color contrast between the background and foreground affects the readability of the content. If the contrast is too small, the text and background can flow into one another and so the text disappears or becomes difficult to read for people with different types of color deficits or people who are using monochrome displays.

• Ensure that foreground and background color combinations provide sufficient contrast for navigation.
• Dark and light contrast shall be used on all occasions.
• The contrast ratio should be at least 5 to 1 for normal text, and 3 to 1 for large bold text.
