The color #2150C5, also known as Cerulean Blue, presents some accessibility challenges, primarily due to its relatively low luminance. When used as a background color, it's crucial to ensure that the text layered on top has sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This can be verified using online contrast checkers. Lighter text colors, such as white or very light grays, are generally necessary to achieve adequate contrast. Avoid pairing #2150C5 with darker shades, as readability will be significantly impaired. In scenarios where color conveys important information, always provide alternative cues like text labels or icons to accommodate users with color vision deficiencies. Careful consideration of color pairings and luminance contrast is essential for creating inclusive and accessible designs.
