The use of such a dark color has a tendency to create a feeling of trust and elegancy. However, accessibility must be taken into account when designing for the end user.

The hex color #1517D1, a deep dark blue, presents significant accessibility challenges, primarily due to its low luminance. When used as a text color, it requires a very light background to ensure sufficient contrast for readability, complying with WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color might not be suitable for critical information or extensive blocks of text, especially for users with visual impairments. When used for interactive elements such as buttons or links, providing clear visual cues beyond color alone (e.g., underlines, borders, or icons) is crucial to ensure usability for all users. Careful consideration of colorblindness is also important; this dark blue may appear similar to other dark shades for individuals with certain types of color vision deficiency. Testing with accessibility tools and obtaining feedback from users are recommended to validate the design's accessibility.
