The color #0A188E, a deep ultramarine, presents some accessibility challenges, especially in text-based applications. Its low luminance value requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for text to be legible. When using #0A188E as a background color, it's essential to pair it with a light-colored text (e.g., white or very pale yellow) to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using it for interactive elements like buttons or links requires even greater attention to contrast to ensure users can easily identify and interact with them. Avoid using #0A188E for small icons or intricate details, as its darkness can make these elements difficult to discern. For decorative purposes, the contrast requirements are less stringent, but it's always best to err on the side of caution and prioritize accessibility whenever possible.
