The color #1C1BBB, also known as Persian Blue, presents some accessibility challenges, particularly when used as a background or text color. Its relatively low luminance value means that it requires careful consideration of contrast ratios to ensure readability and usability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. When pairing #1C1BBB with text, a light color such as white or a very pale yellow would be necessary to meet these contrast requirements. Using darker colors for text on a #1C1BBB background would likely result in insufficient contrast, making the text difficult to read. To enhance accessibility, consider using this color sparingly or in combination with other colors that provide sufficient contrast. Tools are available online to check contrast ratios and verify compliance with accessibility standards.
