This can make it difficult for users with visual impairments, such as those with low vision or color blindness, to read content effectively. Web developers should avoid using #180133 for text or important UI elements unless paired with a very light color that ensures a contrast ratio meeting WCAG (Web Content Accessibility Guidelines) standards, ideally a ratio of 4.5:1 for normal text and 3:1 for large text. Consider alternative, lighter shades or employing color contrast analysis tools to guarantee accessibility. Sufficient contrast is crucial for a positive and inclusive user experience.
