The hex color #1D0A91, also known as Ultramarine, presents some accessibility challenges, primarily due to its dark hue. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). It's crucial to test the color combination using accessibility tools to verify compliance. Avoid pairing it with other dark colors or muted tones, as this can lead to low contrast and make content difficult for users with visual impairments to perceive. Consider providing alternative high-contrast themes for users who need them. Using this color for decorative elements should be done sparingly and not for conveying essential information.
