The hex color #2457B2, also known as Cerulean Blue, presents some accessibility challenges, particularly in text applications. Its relatively low lightness value results in a lower contrast ratio against white backgrounds, which can make it difficult for users with visual impairments to read text rendered in this color.

When using #2457B2 for text, it's crucial to ensure sufficient contrast by pairing it with a light background color like white (#FFFFFF) or a very light gray. Alternatively, using a darker shade of blue or black text on a #2457B2 background can improve readability. Consider utilizing accessibility evaluation tools to assess the contrast ratio and ensure compliance with WCAG guidelines. Proper attention to color contrast enhances the user experience for all individuals, regardless of their visual abilities.
