The hexadecimal color code #1F17CF is often used in digital design to represent this particular shade of blue. Colors like this one are formed by mixing red, green and blue light where the relative quantities of red, green and blue determine the hue.

The color #1F17CF, a deep shade of blue, presents significant accessibility challenges, particularly regarding contrast. When used as text against a white background, it falls far short of WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. This means that users with visual impairments, such as low vision or color blindness, may struggle to read the text. To improve accessibility, consider using #1F17CF for decorative elements or backgrounds, paired with white text. Alternatively, choose a much lighter shade of yellow, orange, or green as a background. Always use contrast-checking tools to verify that color combinations meet accessibility standards and ensure content is usable for everyone.
