The hex color #1B2A80, also known as Jackson's Purple, is a deep, muted shade of purple that conveys a sense of sophistication and mystery. It belongs to the family of blue-violet colors and has a relatively low saturation, which contributes to its subdued and calming effect. In the RGB color model, it is composed of 10.6% red, 16.5% green, and 50.2% blue. This color is often associated with royalty, luxury, and creativity. Its unique blend of blue and purple makes it versatile for use in various design contexts, from web development to interior design. Because it is a dark color, it is not readable on its own and should be paired with lighter colors to ensure readability and accessibility.

The hex color #1b2a80, also known as Jackson's Purple, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in low contrast against lighter backgrounds, making text or interactive elements difficult to discern. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #1b2a80, it's imperative to pair it with a very light color, such as white or a pale yellow, to ensure adequate contrast. Tools like contrast checkers can help evaluate compliance with accessibility standards. Furthermore, avoid using this color for essential visual cues or links without additional indicators like underlines or icons, as color alone should not convey critical information. Providing alternative text descriptions for images and ensuring keyboard navigation support are also essential practices to improve accessibility for all users.
