The color #2D4AC4, also known as Cerulean Blue, presents some accessibility challenges. Its relatively low luminance can result in insufficient contrast against light backgrounds, making text or interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #2D4AC4, it's crucial to ensure that the foreground and background colors provide adequate contrast. Using a lighter shade of yellow or white text on the blue background, for instance, improves legibility. Tools like contrast checkers can help evaluate and adjust color combinations to meet accessibility standards, ensuring inclusive design for all users, including those with low vision or color blindness.
