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.
