The color #0A168E, a deep ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color, it requires a very light background to ensure sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This dark blue shade may struggle to meet these ratios with many common background colors. Therefore, careful consideration is needed in selecting appropriate accompanying colors. Using tools to measure color contrast is crucial to ensure that the content is accessible to a wide range of users. It’s advisable to pair it with colors like #FFFFFF (white) or very light shades of yellow or gray to achieve the necessary contrast levels. Also, avoid using it for crucial UI elements without proper contrast, as it can lead to a poor user experience.
