The hex color #00304D, also known as Blue Whale, presents specific accessibility challenges, especially when used as a background or text color. Its low luminance value of approximately 4.5% means that it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet Level AA compliance. For Level AAA, the contrast ratios should be even higher (7:1 and 4.5:1 respectively). Using #00304D for important textual information without considering these contrast ratios can lead to a poor user experience, particularly for individuals with visual impairments or color blindness. When designing with #00304D, careful consideration must be given to the color of the foreground elements to ensure they meet accessibility standards. Tools like contrast checkers can be used to verify compliance.
