We comply with AA standard contrast ratios. To do this, we choose primary, secondary and extended colors that support usability. This ensures sufficient color contrast between elements so that people with low vision can see and use our products.
Don't convey information using color alone. Use multiple visual cues, such as stroke weight, patterns, shape, text, or illustrations to ensure that everyone receives the same information. This helps people who are unable to, or have difficulty with, distinguishing one color from another. This includes people who are color blind, have low vision, or are blind.
High color contrast helps people who are partially or completely color blind see differences between certain colors. It creates a strong visual hierarchy and improves usability for everyone. Make sure that the combination of text and background color do not fall below the WCAG recommended threshold ratio of 4.5:1 for standard text and 3:1 for larger text.
