The hex color #0D158E, a deep ultramarine, presents significant accessibility challenges. Its low luminance value of 4.59 cd/m² results in poor contrast against standard white backgrounds, failing WCAG 2.0 Level AA and AAA standards for normal text. This poses readability issues for users, especially those with visual impairments. To improve accessibility, consider using lighter text colors like white (#FFFFFF) to increase contrast. Alternatively, the color can be paired with darker backgrounds to create a visually balanced interface. Utilizing contrast checker tools to ensure compliance with WCAG guidelines is crucial for inclusive design practices. A higher contrast ratio ensures that text and interactive elements are easily distinguishable, thereby enhancing the user experience for everyone, including those with disabilities.
