The hex color #083155, a deep shade of Prussian Blue, presents significant accessibility challenges, particularly for text-based content. Its very low luminance value (darkness) necessitates careful consideration of contrast ratios against background colors. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive text and other essential elements clearly. A light background is absolutely essential; avoid pairing this color with other dark shades. Large text requires a contrast ratio of at least 3:1, while regular text needs 4.5:1. Using online contrast checkers can help ensure compliance. Furthermore, rely not solely on color to convey information. Always provide redundant cues like labels or icons. Screen reader users cannot perceive color, thus clear and concise semantic HTML is important.
