The hex color #1f53c7, also known as Cerulean Blue, presents some accessibility challenges, primarily due to its relatively low luminance. When used as a foreground color, it necessitates careful consideration of the background color to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #1f53c7 on a white background, for example, may not meet these standards, potentially causing readability issues for users with visual impairments. To improve accessibility, consider using a lighter shade of yellow or white as a background. It is crucial to test color combinations using accessibility tools to ensure compliance with accessibility standards and provide a positive user experience for everyone, including those with disabilities.
