The color #0A118E, a deep ultramarine, presents several accessibility considerations for web design. Due to its low luminance, it requires careful pairing with contrasting colors to ensure readability. As a dark color, it should ideally be used with light text to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. For body text, a contrast ratio of at least 4.5:1 is recommended, while larger text elements can adhere to a 3:1 ratio. Insufficient contrast can make content difficult to read, especially for users with visual impairments. Using tools to check contrast ratios is essential. Also, avoid using this color for crucial interactive elements without sufficient visual cues or labels, as it might be hard to distinguish for users with color blindness or low vision.
