The hex color #2B3EE8, also known as Cerulean Blue, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, it may not meet the WCAG (Web Content Accessibility Guidelines) AA standard for contrast ratio, which requires a minimum contrast ratio of 4.5:1 for normal text. Similarly, when used on darker backgrounds, the contrast needs careful evaluation. To ensure accessibility, designers should pair this color with either very light or very dark colors to achieve sufficient contrast. Tools like WebAIM's Contrast Checker can be useful in verifying contrast ratios. Additionally, providing alternative visual cues, such as underlines or icons, for links or interactive elements can enhance accessibility for users with visual impairments. Considering the needs of users with color blindness is also crucial. Avoid using color alone to convey important information; instead, use text labels or patterns as supplementary indicators. Testing with color blindness simulators can help identify potential issues.
