The hex color #1B4ECB, a shade of Cerulean Blue, presents some accessibility challenges for web developers. Its relatively low luminance can cause contrast issues when used as text against a white or very light background. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #1B4ECB for text may require careful consideration of the background color to ensure readability.
