The color #190C8C, also known as Ultramarine, presents several accessibility considerations for web developers. Due to its dark nature, it is imperative to use it with light-colored text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Testing the color combination with accessibility tools is highly recommended to verify compliance. When using this color for interactive elements, such as buttons or links, providing clear visual cues for hover, focus, and active states is crucial.
