The color #100494, a deep Ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its low luminance value of approximately 2 means that it provides very little contrast when paired with lighter colors like white or yellow. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. To ensure accessibility, #100494 should ideally be used with a high contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. When using this color for text, consider pairing it with very light shades. Avoid using it for critical information or interactive elements unless sufficient contrast can be guaranteed. Using color contrast checkers can help to determine whether a color combination meets accessibility standards.
