The color #1D0F8C, a deep ultramarine, presents some accessibility considerations for web design. Its low luminance value means it requires careful pairing with text and background colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #1D0F8C as a background, pairing it with white or a very light color is crucial. Conversely, as text, it should be placed against a very light background. Insufficient contrast can cause readability issues, especially for users with visual impairments. Tools like contrast checkers can help evaluate color combinations. Beyond contrast, consider the psychological impact; deep blues can evoke feelings of seriousness, stability, and trust, but overuse might feel somber.
