The hex color #081188, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely dark nature results in very low contrast against typical light backgrounds. This makes text and other elements using this color difficult to read. Web developers should avoid using #081188 for text or essential interactive elements unless paired with a very light or white color to ensure a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards, ideally a ratio of 4.5:1 for normal text and 3:1 for large text. Careful consideration should be given to users with color blindness, as the lack of luminance contrast can further impede readability. Providing alternative high-contrast themes or allowing users to customize colors can greatly improve the accessibility of content using this dark shade of blue.
