The hex color #180A27, also known as Vulcan, presents significant accessibility challenges, especially in text-based applications. Its extremely dark hue results in very low contrast against standard light backgrounds, making it difficult for users with visual impairments to read text rendered in this color. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability. To improve accessibility, web developers should avoid using #180A27 for text or interactive elements on light backgrounds. If this color is essential for branding purposes, consider using it sparingly and always paired with a light color that provides adequate contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools such as contrast checkers can assist in evaluating the compliance of color combinations.
