The hex color #2257B4, also known as Cerulean Blue, presents some accessibility considerations for web development. Its relatively low luminance means that careful attention must be paid to contrast ratios, particularly when used as a background or foreground color for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). When using #2257B4 for text, it is advisable to pair it with a light color such as white (#FFFFFF) or a very light shade of gray to ensure sufficient contrast. Tools like the WebAIM contrast checker can be used to verify compliance with accessibility standards. Avoid using this color for small text or crucial interactive elements without carefully considering the contrast.
