A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) standards. Utilizing tools to check color contrast ratios is crucial. Avoid pairing this dark blue with other dark colors, as this will significantly reduce visibility.

Proper implementation of ARIA attributes and semantic HTML can further enhance accessibility, providing alternative ways for users to understand content even if they struggle with the color contrast. Additionally, providing alternative high-contrast themes or allowing users to customize colors can greatly improve the experience for those with visual impairments.
