Its low luminance value (approximately 0.02) means that it requires very light text (white or near-white) to achieve acceptable contrast ratios as defined by WCAG (Web Content Accessibility Guidelines). A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #1B0CA6 with dark or even moderately dark text will likely fail these contrast tests, making the content difficult or impossible for users with visual impairments to read.
