The hex color #1B1F99, also known as Jacksons Purple, presents some accessibility challenges, particularly when used as a background or foreground color for text. Its low lightness value (relative luminance) results in a poor contrast ratio against standard white text (#FFFFFF). This can make it difficult for users with visual impairments to read content. To ensure accessibility, it is crucial to use a light or bright color like white, yellow, or light green for text displayed on a #1B1F99 background. Utilizing online contrast checkers is a great method to test the contrast ratio between the foreground and background colors to meet WCAG (Web Content Accessibility Guidelines) standards. A minimum contrast ratio of 4.5:1 is recommended for normal text and 3:1 for large text to comply with AA standards. Using this color requires careful consideration of its visual impact to create an inclusive design for all users.
