The hex color #224CB4, Cerulean Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it's crucial to pair it with text that offers sufficient luminance contrast to ensure readability for individuals with visual impairments. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Therefore, avoid using #224CB4 with lighter shades of blue, green, or gray, as these combinations are likely to fail accessibility checks. White or very light yellow text generally provides better contrast. Also, ensure that interactive elements using this color, such as buttons or links, have clear visual cues beyond just color to distinguish them from the surrounding content.
