The hex color #170299, also known as Ultramarine, presents certain accessibility challenges, particularly concerning color contrast. When using this color for text or interactive elements, it's crucial to ensure sufficient contrast against the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Due to its dark nature, #170299 requires a light background to meet these standards. Using a color contrast checker is highly advisable to verify compliance. Furthermore, relying solely on color to convey information should be avoided. Providing alternative cues, such as text labels or icons, ensures that users with color vision deficiencies can still understand and interact with the content effectively. Consideration should also be given to users with low vision, who may benefit from adjustable text sizes and high-contrast themes.
