The hex color #2A4FBC, also known as Cerulean Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color for text, it requires careful consideration of the background color to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Pairing Cerulean Blue with very light colors like white or pale yellow might fall short of these recommendations, potentially causing visual strain for users, especially those with visual impairments. Therefore, it's advisable to use darker shades or complementary colors for backgrounds to achieve adequate contrast and ensure a more inclusive and accessible design. Tools like contrast checkers can be helpful in evaluating and adjusting color combinations.
