The hex color #2B5EBB, also known as Cerulean Blue, presents some accessibility considerations for web developers. With a relatively low luminance, it may pose challenges for users with visual impairments, particularly when used as text against a white background. To ensure readability, a strong contrast ratio is crucial. Aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, as recommended by WCAG guidelines. Consider using a lighter color for text on a #2B5EBB background, or a darker shade for the background when #2B5EBB is used for text. Tools like contrast checkers can assist in evaluating color combinations. It's also important to consider users with color blindness and test the color scheme using simulations to ensure information is still conveyed effectively.
