The color #1807AD, also known as Ultramarine, presents some accessibility challenges, particularly for users with visual impairments. Its low lightness value (relative luminance of approximately 0.02) means that it requires very light text or foreground elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #1807AD as a background, careful consideration should be given to the choice of text color to meet these standards. White (#FFFFFF) or very light shades of gray would be appropriate choices. Tools like contrast checkers can be used to verify compliance. Additionally, avoid using this color for essential information or interactive elements without proper contrast, as it may be difficult for users to perceive. Also, users with color vision deficiencies may struggle to differentiate this shade from other dark blues or purples. Consider providing alternative visual cues or relying on textual labels to convey meaning.
