Due to its dark nature, it demands careful consideration of contrast ratios. When used as a background color, it is crucial to pair it with a light foreground color, such as white or a very pale yellow, to ensure readability for individuals with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as per WCAG guidelines. Using color contrast analyzers can help verify compliance. Avoid pairing #0A0E8E with other dark colors, as this will create insufficient contrast, making content difficult to perceive. In interactive elements, consider providing additional visual cues beyond color to ensure usability for colorblind users.
