The color #214EC5, also known as Cerulean Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance (brightness) of approximately 11 cd/m² means it might not provide sufficient contrast against lighter backgrounds, making text or user interface elements difficult to read. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast is essential for readability. For standard text (size 14 points or 18 pixels and larger), a contrast ratio of 4.5:1 is recommended, while for large text (size 18 points or 24 pixels and larger), a ratio of 3:1 is considered acceptable. When using #214EC5, careful consideration should be given to the background color to ensure these contrast ratios are met. It's advisable to use contrast checking tools to verify compliance. Additionally, avoid using this color to convey critical information without alternative visual cues, as colorblind users may not perceive it accurately. Pairing it with a very light or white color is recommended for improved accessibility.
