The color #2E5FB8, also known as Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white text is approximately 3.8:1, falling short of the WCAG AA recommendation of 4.5:1 for normal-sized text, meaning users with moderate visual impairments may find it difficult to read. However, it meets the WCAG AA standard for large text (at least 18pt or 14pt bold) with a contrast ratio of 3:1. When used as a background color, ensure sufficient contrast by using lighter text colors like white or very light grays. Careful consideration should be given to the text size, font weight, and the overall design context to make the content accessible to a wider audience. For users with color vision deficiencies, this blue might be perceived differently. Therefore, avoid relying solely on color to convey important information; use text labels and icons as redundant indicators. Tools like contrast checkers can help assess and improve the color's accessibility.
