The hex color #0A1891, also known as Ultramarine, presents some accessibility considerations for web developers. Due to its deep, saturated hue, it's crucial to ensure sufficient contrast when used as either a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Pairing #0A1891 with lighter colors such as whites (#FFFFFF) or lighter shades of yellow or green can help achieve this. Avoid using it with similarly dark colors, as the contrast may be insufficient for users with visual impairments. Additionally, consider providing alternative visual cues beyond color alone to convey information, as colorblind users may struggle to distinguish #0A1891 from other dark colors. Thorough testing with accessibility tools and real users is recommended to ensure optimal usability.
