The color #1E53B8, a shade of cerulean blue, presents moderate accessibility challenges. Its contrast ratio against white is approximately 4.6:1, which meets WCAG AA standards for normal text but falls short of AAA standards. For larger text (14pt bold or 18pt regular), it meets the AA standard. When used as a background color, ensure that the foreground text is sufficiently light to provide adequate contrast. Consider using a lighter shade of blue or a neutral color like white or a very light gray for text. This will improve readability, especially for users with visual impairments. Also, avoid using this color as the sole indicator of interactive elements, as colorblind users may not be able to distinguish them. Supplement with text labels or icons. Testing with accessibility tools is recommended.
