The hex color #214DB5, also known as Cerulean Blue, presents some accessibility challenges. With a relatively low luminance, it may not provide sufficient contrast against lighter backgrounds, potentially making text or interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for ensuring readability and usability. When using this color for text, it's essential to pair it with a very light color to meet the contrast ratio requirements (at least 4.5:1 for normal text and 3:1 for large text). Tools like contrast checkers can help determine if the color combination meets accessibility standards. Additionally, consider providing alternative visual cues, such as icons or labels, to convey information, especially for users with color blindness. Testing with different color blindness simulators can also help ensure that the color is distinguishable for all users. Using this color for decorative purposes is less critical, but still should be taken into account, to provide the best user experience.
