The color #1B40BB, also known as Persian Blue, presents some accessibility challenges, especially when used as a foreground color on a white background or vice versa. Its contrast ratio might not meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast, particularly for users with low vision or color blindness. To improve accessibility, consider using it with lighter shades of yellow or green, as these colors typically offer better contrast. Also ensure that text using this color is at least 14 points and bold or 18 points if it's regular weight. Providing alternative text and visual cues is crucial. Tools like contrast checkers can help verify that the color combination meets accessibility requirements, ensuring a more inclusive user experience. Using a slightly lighter shade of this color or darkening the background can also significantly improve contrast ratios and overall readability.
