The hex color #1B49CB, also known as Cerulean Blue, presents some accessibility challenges. Its relatively low luminance makes it difficult to read text with a small font size when used as a text color on a white background. According to WCAG guidelines, this color combination may not meet the minimum contrast ratio for level AA compliance, especially for users with visual impairments. When using this color for text or interactive elements, it is crucial to choose a lighter background color or to increase the font size to improve readability. Consider using tools to check the contrast ratio and ensure it meets accessibility standards for your target audience. Furthermore, provide alternative ways to convey information, such as icons or descriptive text, to make the content more accessible.
