When using this dark blue as a background, it's crucial to select a text color that provides sufficient contrast to ensure readability for individuals with visual impairments. A light color such as white or a very light yellow or gray is generally recommended. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. It is important to test color combinations using accessibility evaluation tools to verify compliance. When using #0A3D8C for text, the same contrast principles apply, requiring a light background for optimal readability. Considering users with color vision deficiencies is also important; therefore, relying solely on color to convey information should be avoided. Supplementing color cues with text labels or other visual indicators can improve accessibility for all users. Careful consideration and testing are essential to ensure that content is accessible and inclusive.
