The color #190BA8, Ultramarine, presents some accessibility challenges, primarily due to its low lightness value. When used as a background color, it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to comply with WCAG guidelines. Using this color for interactive elements like buttons or links requires careful consideration. Ensure that hover and focus states are clearly distinguishable with adequate contrast. Avoid pairing Ultramarine with other dark colors, as this will further reduce contrast and make the content inaccessible to users with visual impairments. Tools like contrast checkers can help verify compliance with accessibility standards. Furthermore, consider the cognitive impact of using such a saturated color. Some users may find it visually overwhelming, so use it judiciously, especially for large blocks of text or complex interfaces.
