The hex color #2152C5, also known as Cerulean Blue, presents some accessibility challenges, particularly regarding color contrast. When used as a background color, it's essential to choose text colors with sufficient luminance contrast to ensure readability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. White text on a Cerulean Blue background may not always meet these standards, so testing with accessibility tools is crucial. Consider using lighter shades of blue or complementary colors like yellow as alternatives for backgrounds or foregrounds to enhance contrast and improve the overall user experience. Also, avoid relying solely on color to convey important information, as colorblind users may not be able to perceive the difference. Supplement color cues with text labels or icons.
