The color #1E4AB8, a deep cerulean blue, presents some accessibility challenges, primarily due to its relatively low luminance. When used as a background color, it's crucial to ensure sufficient contrast with the foreground text or elements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to comply with WCAG 2.1 AA standards. Utilizing online contrast checkers can help verify compliance. For users with visual impairments, including those with low vision or color blindness, inadequate contrast can make content difficult or impossible to perceive. Consider pairing this color with lighter shades of yellow, white, or even a contrasting light blue to enhance readability and overall accessibility. Furthermore, avoid relying solely on color to convey important information; use supplementary cues like text labels or icons to ensure all users can understand the content, regardless of their color perception abilities.
