The color #010197, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value results in poor contrast against light backgrounds, making text or graphical elements difficult to discern. To ensure readability, it is crucial to pair this color with very light shades. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as per WCAG guidelines. Using color alone to convey information should be avoided; supplementary cues like text labels or icons are essential. Consider providing alternative color schemes that offer better contrast for users with low vision or color blindness. Testing with accessibility tools is imperative to validate the usability of any design incorporating this dark hue.
