The color #090B8F, a deep ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its extremely low luminance value of approximately 0.003 makes it difficult to achieve sufficient contrast against lighter backgrounds. 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 this color, only very light shades of white or yellow would likely meet these contrast requirements. Developers should exercise caution and rigorously test color combinations to ensure readability. Using this color for text on a dark background is strongly discouraged. If used as a background, ensure that the foreground elements have sufficient contrast and are easily distinguishable. Furthermore, consider providing alternative color schemes to accommodate users with diverse visual needs, such as those with color blindness or low vision. Relying solely on color to convey information is also discouraged; supplement with text labels or other visual cues.
