It is also a popular choice in data visualization, where its distinct hue can help to differentiate between various data sets and highlight key insights.

The color #0166C9, or Science Blue, presents accessibility challenges due to its relatively low luminance. When used as a foreground color, it requires careful consideration of the background color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between foreground and background colors should be at least 4.5:1 for normal text and 3:1 for large text to meet Level AA compliance. For Level AAA compliance, these ratios increase to 7:1 and 4.5:1 respectively. When using #0166C9 for text or interactive elements, it is essential to pair it with a very light background color such as white (#FFFFFF) or a very light gray to ensure sufficient contrast. Avoid using it against dark backgrounds, as this will result in very poor readability. Tools like contrast checkers can help you verify the contrast ratio. For graphical elements and user interface components, a contrast ratio of 3:1 is required. It's good to provide alternative ways to identify elements such as icons or shapes and avoid relying solely on color.
