The hex color #001B80, also known as Resolution Blue, presents some accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 3% means that text rendered in this color on a white background (or any light background) will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. To ensure readability, consider using #001B80 with very light text (such as #FFFFFF or #F0F0F0) or pair it with a much darker background color like black (#000000) to achieve sufficient contrast. Careful consideration should be given to users with color vision deficiencies; ensure that critical information isn't conveyed solely through color. Supplement color cues with text labels or other visual indicators. When using this color for interactive elements, provide clear focus states to aid keyboard navigation.
