The hex color #2155B5, also known as Cerulean Blue, presents some accessibility considerations for web developers. When used as a background color, it's crucial to ensure sufficient contrast with the foreground text. A light text color, such as white or a very pale yellow, is recommended to meet WCAG guidelines for contrast ratios (minimum 4.5:1 for normal text and 3:1 for large text). Using online contrast checkers is essential to verify compliance. Additionally, avoid relying solely on color to convey important information, as colorblind users may not perceive it accurately. Providing alternative cues like text labels or icons will enhance the user experience for everyone. Consider the cognitive load as well; too much bright color can be overwhelming for some users, so balance is key. If Cerulean Blue is used for interactive elements, ensure that hover and focus states are clearly distinguishable to aid keyboard navigation and provide visual feedback.
