The color #220CA8, a deep ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a high contrast ratio when paired with light text, ensuring readability for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text according to WCAG guidelines. When using this color for backgrounds, it is crucial to select a foreground text color that meets these contrast requirements to ensure accessibility for all users. Tools like contrast checkers can assist in verifying sufficient contrast. Additionally, avoid using this color as the sole means of conveying information; supplement it with text labels or other visual cues to ensure usability for users with color blindness.
