The color #0B41A9, a deep cobalt blue, presents some accessibility challenges, especially in text applications. Its relatively low luminance (brightness) means that it requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, sufficient contrast is essential for text and interactive elements. When using #0B41A9 as a background, it is imperative to pair it with a light-colored text (e.g., white or a very pale yellow) to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Conversely, if #0B41A9 is used for text, a much darker background is needed. Testing with accessibility tools is recommended to confirm compliance. Avoid using this color for critical information or actions without ensuring adequate contrast. Also, consider providing alternative styling options for users who need them.
