The color #0B3DA9, also known as Cobalt, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it requires light-colored text to ensure readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. Given Cobalt's darkness, a white or very light gray text would be appropriate. It's crucial to test the color combination with accessibility tools to confirm compliance. Also, avoid using this color as the sole indicator of interactive elements or important information, as users with visual impairments might not be able to distinguish it effectively. Consider adding supplementary cues like icons or text labels to enhance usability for everyone.
