The hex color #2747BF, a shade of cerulean blue, presents some accessibility challenges. Its relatively low luminance necessitates careful consideration of text and background combinations. When used as a background color, it is crucial to pair it with light-colored text, such as white (#FFFFFF) or a very light gray, to ensure sufficient contrast for readability. Conversely, if used for text, a dark background is essential. 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 to meet AA compliance. Employing contrast checking tools is highly recommended to verify compliance and make necessary adjustments. Consideration should also be given to users with visual impairments or color blindness, potentially requiring alternative color schemes or visual cues to convey information effectively.
