The color #0D308B, also known as Resolution Blue, presents some accessibility challenges, primarily due to its low luminance. When used as text on a white background, it may not meet WCAG (Web Content Accessibility Guidelines) AA standards for contrast ratio. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using this color for text requires careful consideration and testing with accessibility tools to ensure readability for users with visual impairments. To improve accessibility, consider using a lighter background or a lighter shade of blue for the text. Also, avoid using this color for small, important user interface elements, such as buttons or icons, without sufficient contrast. Providing alternative text descriptions for images using this color is important. Offering user-adjustable color schemes can significantly improve the accessibility of content using this dark blue.
