The hex color #150ea6, also known as Ultramarine, presents some accessibility challenges, particularly in text-based applications. Its dark hue means it requires light text to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #150ea6 as a background, it's essential to pair it with text colors like white or light yellow to meet these standards. Tools like contrast checkers can help verify compliance. Moreover, consider users with visual impairments; avoid using color as the sole means of conveying information. Providing alternative cues like icons or labels ensures broader accessibility. For interactive elements like buttons, ensure sufficient size and clear visual cues for focus states.
