The color #170BBF, a deep dark blue, presents some accessibility challenges, especially when used as text on a white background. Its low luminance value of approximately 0.02 makes it difficult to read for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. Using #170BBF as text on a white background results in a contrast ratio significantly lower than these recommendations. To improve accessibility, it is advisable to pair this color with lighter shades like whites, yellows, or light greens, which provide sufficient contrast. Alternatively, when #170BBF is used as a background color, the text should be a lighter hue to ensure readability. Proper color contrast is crucial for users with low vision or color blindness, enabling them to perceive content effectively and ensures a more inclusive user experience.
