The color #09168F, a deep ultramarine, presents accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 2 means it offers insufficient contrast against common background colors like white. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. When using this color for text, ensure a background color with a significantly higher luminance is paired with it. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Moreover, avoid relying solely on color to convey important information, as colorblind users may struggle to distinguish it. Supplement color cues with text labels or icons to ensure inclusivity and universal access. Careful consideration of color combinations is essential for making web content accessible and user-friendly for everyone.
