The hex color #02355B, also known as Prussian Blue, presents some accessibility challenges, particularly concerning color contrast. When using this color for text or interactive elements, it's crucial to ensure sufficient contrast against the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Given the darkness of Prussian Blue, it is best paired with light colors such as white, light gray, or pale yellow to meet these guidelines.

Failure to provide adequate contrast can render content unreadable for individuals with visual impairments. Furthermore, avoid using color alone to convey important information; supplement it with text or other visual cues to ensure inclusivity.
