Of course, it is the first option. Isn’t it? Because it is more clearly visible to human eyes. We humans are more attracted to colors than words. So you have to carefully choose the colors to use on your website.

Contrast ratio plays an important role in your website. When you have specially-abled users visiting your website you have to be more specific about the colors used on your website.

This is where accessibility contrast checker will make your job easy. It checks different combinations of foreground and background colors and suggests you the best one.

You can use a contrast checker before you build your website. Or you can also use it for testing the accessibility of your website.

WCAG defines certain standards for the contrast ratio of a website:

  • Level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text.
  • WCAG 2.1 requires a contrast ratio of at least 3:1 for graphics and user interface components.
  • Level AAA requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text.
