The color #170BCB, a deep shade of blue, presents accessibility challenges for web content. Its low luminance value of 0.029 means that text using this color as a foreground element requires careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background. Due to its darkness, #170BCB needs to be paired with very light colors like white or pale yellow to meet these standards. Failure to do so can result in readability issues, especially for users with visual impairments. When using this color, providing alternative high-contrast themes or allowing users to adjust color schemes is crucial for ensuring inclusive design. Also, avoid using it for critical information elements without sufficient contrast.
