The color #00185D, also known as Gulf Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of 2.14 makes it difficult to perceive against many background colors. According to WCAG guidelines, to ensure readability and usability, sufficient contrast between text and background is crucial. When using #00185D for text, it's essential to pair it with a very light color, such as white or a pale yellow, to achieve a contrast ratio that meets at least the AA standard (4.5:1) or ideally the AAA standard (7:1). Avoid using it for small text or essential UI elements against dark or mid-tone backgrounds, as this can render them illegible. Consider providing alternative high-contrast themes or options for users to customize the color scheme according to their preferences and needs.
