The hex color #0B3390, a deep shade of blue, presents some accessibility challenges primarily related to color contrast. When used as a foreground color for text, it requires careful consideration of the background color. According to WCAG guidelines, sufficient contrast is crucial for readability, especially for users with visual impairments. A light background is essential to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Conversely, when used as a background color, pairing it with a light foreground color like white or a very light yellow can ensure good readability. Avoid using this color with mid-tone or dark colors, as the resulting contrast will likely be insufficient, making the text difficult to read. It's advisable to use color contrast checking tools to ensure compliance with accessibility standards.
