This particular shade of blue is often used in branding, graphic design, and web development to create a sense of professionalism and reliability. It’s a visually striking color that can add a touch of elegance to a variety of applications. Due to its deep tone, it is often used as an accent color rather than the primary color in designs.

The color #1B37AF, a deep Persian Blue, presents considerable accessibility challenges. Its low luminance value of 0.14 makes it difficult to use as text against a white background. According to WCAG guidelines, it fails both the AA and AAA contrast ratios for normal text, requiring a contrast ratio of at least 4.5:1 and 7:1 respectively. Even for large text, it barely meets the AA standard, with a contrast ratio of approximately 3.6:1. To enhance accessibility, consider using #1B37AF with lighter background colors such as white, light grey, or very pale yellow. Pairing it with brighter accent colors or using it sparingly for decorative elements rather than primary text or interactive components will also improve usability for individuals with visual impairments. Adequate testing with assistive technologies is recommended to validate accessibility.
