The hex color #224EC4, also known as Cerulean Blue, presents some accessibility considerations for web development. Its luminance value is relatively low, which means it needs to be carefully paired with text and background colors 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. When using #224EC4 as a background color, it's crucial to use light-colored text to meet these contrast requirements. Conversely, if used as text, a very light background is necessary.
