It is characterized by its strong saturation and relatively low lightness, giving it a rich and intense appearance. In the RGB color model, #1B39CB is composed of 10.6% red, 22.4% green, and 79.6% blue. This combination of primary colors creates a distinct and recognizable hue. The color is often associated with qualities such as trust, stability, and intelligence, making it a popular choice for branding and design applications. Historically, the name 'Persian Blue' is derived from the color's prevalence in Persian art, ceramics, and textiles. In color psychology, blue is often linked to feelings of calmness, serenity, and security.

The color #1B39CB, also known as Persian Blue, presents significant accessibility challenges, particularly for users with visual impairments or color vision deficiencies. Its low luminance value of approximately 14% relative to white makes it difficult to discern text or user interface elements rendered in this color against a white background. A contrast ratio of at least 4.5:1 is recommended by WCAG guidelines for normal text, and 3:1 for large text, to ensure readability. When used for text, #1B39CB should be paired with a very light color such as white (#FFFFFF) or a light yellow (#FFFFE0) to meet these contrast requirements. Avoid pairing it with mid-tone or dark colors, as this will result in insufficient contrast. For graphical elements and user interface components, ensure a contrast ratio of at least 3:1 against adjacent colors. It's also crucial to consider users with color blindness; relying solely on color to convey information should be avoided. Provide alternative cues, such as text labels or icons, to ensure inclusivity.
