Due to its low luminance, it requires careful consideration to ensure sufficient contrast with foreground elements. A light text color, such as white or a very pale yellow, is essential to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Using contrast checking tools is highly recommended to verify compliance, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid pairing this dark blue with other dark colors, as this will create readability issues. Consider providing alternative color schemes for users with visual impairments or color blindness to enhance accessibility.
