The name 'Cerulean' itself is derived from the Latin word 'caeruleus', which means 'sky blue' or 'dark blue'.
The color #2B4ABB, also known as Cerulean Blue, presents some accessibility challenges, especially concerning color contrast. When used as text on a white background, the contrast ratio might not meet WCAG (Web Content Accessibility Guidelines) standards for Level AA compliance, which requires a contrast ratio of at least 4.5:1 for normal text. This could make it difficult for users with visual impairments to read the content. Therefore, it is crucial to pair Cerulean Blue with a very light color or white as a background or a very dark color as text to ensure readability. For example, consider using a light yellow or off-white as the background color or using black or a dark grey as the text color. Additionally, providing alternative cues like underlining links or using icons alongside text can further enhance accessibility for all users.
