The hex color #10128b, also known as Ultramarine, presents specific accessibility challenges, particularly in text and user interface design. Due to its dark nature, it requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for standard text and 3:1 for large text against its background. Using #10128b as a background color necessitates light text colors like white (#FFFFFF) or very light grays to meet these standards. Conversely, using it as a text color demands a very light background. It's crucial to test color combinations with accessibility tools to confirm compliance and provide an inclusive experience. Avoid pairing it with mid-tone colors as the contrast will likely be insufficient.
