What is the best contrasting colors for text and background?

Black text on a white background provides maximal value contrast and, therefore, optimal readability for body text. The contrast between charcoal gray (#333333) text and a white background is about eighty percent—thus giving minimally good value contrast.

Is there enough contrast between background colors and font colors?

To make your content accessible, you should have high contrast between all text and its background color. If your text is dark, your background should be light, and vice versa. Black text on a white background is recommended for paragraphs of text.

What is the color contrast rule?

Color contrast is the difference in brightness between foreground and background colors. For accessibility purposes, aim for a 4.5:1 ratio between the foreground color (e.g. text, links, etc.) and the background color. This ratio ensures people with moderately low vision can tell the colors apart and see your content.

How do you determine contrast ratio of color?

Calculating a Contrast Ratio

Contrast ratios can range from 1 to 21 (commonly written 1:1 to 21:1). (L1 + 0.05) / (L2 + 0.05), whereby: L1 is the relative luminance of the lighter of the colors, and. L2 is the relative luminance of the darker of the colors.
