The color #2656B0, or Cerulean Blue, presents some accessibility considerations for web development. Its relatively low lightness value means it requires careful pairing with text and background colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using Cerulean Blue as a background, white or very light shades of yellow or green are often suitable choices for text color. Conversely, if Cerulean Blue is used for text, a white or extremely light background color is necessary. Tools for checking color contrast ratios should be utilized during development to verify compliance with accessibility standards, ensuring that all users, including those with visual impairments, can effectively read and interact with the content. Avoid pairing it with dark colors because that reduces readability. Additionally, consider providing alternative visual cues beyond color alone to convey information, as color blindness affects a significant portion of the population. This can include using icons, patterns, or text labels to supplement the color-coded information.
