The color #170CA8, a deep ultramarine, presents several accessibility considerations for web developers. Its dark hue necessitates careful selection of foreground text colors to ensure sufficient contrast. White or very light shades of yellow or green are generally recommended to meet WCAG (Web Content Accessibility Guidelines) standards for readability. Using a contrast ratio checker is crucial to confirm compliance, aiming for a minimum of 4.5:1 for normal text and 3:1 for large text. Furthermore, when used as a background color, developers should avoid pairing it with similarly dark colors, as this can make content illegible for users with visual impairments. Consideration should also be given to users with color vision deficiencies, as the deep blue may be perceived differently. Providing alternative color schemes or allowing users to customize their display settings can improve accessibility. Also avoid using this color alone to convey information.
