The color #063356, a deep shade of Prussian Blue, presents some accessibility challenges, especially regarding text legibility. When used as a background color, it requires careful consideration of the foreground text color. A light color, such as white (#FFFFFF) or a pale yellow (#FFFFE0), is highly recommended to ensure sufficient contrast. 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. Insufficient contrast can make it difficult for users with visual impairments to read the content. Tools like WebAIM's Contrast Checker can be used to assess the contrast ratio. Additionally, avoid using this color for interactive elements without clear visual cues, as it may be difficult for users to distinguish actionable elements.
