General Information about Persian Blue

The hexadecimal color #311BCB, commonly known as Persian Blue, is a vibrant and intense shade of blue situated in the blue-violet region of the color spectrum. It is composed of 19.2% red, 10.6% green, and 79.6% blue. In the RGB color model, this translates to R:49, G:27, B:203. Persian Blue derives its name from its historical association with Persian art and culture, where similar shades of blue were frequently used in ceramics, textiles, and paintings. The color evokes feelings of serenity, depth, and sophistication. It can be used to represent trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. Because of its intensity and purity, it is suitable to be used as a background color.

The color #311BCB, also known as Persian Blue, presents significant accessibility challenges, particularly in text-based contexts. Its low luminance necessitates careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. When using #311BCB for text, a light background color is crucial to meet these requirements. Conversely, if #311BCB serves as the background, light-colored text is essential. Insufficient contrast can exclude users with low vision or color blindness. Additionally, relying solely on color to convey information is not advisable; supplementary cues such as text labels or icons should be provided to ensure accessibility for all users. Tools like WebAIM's Contrast Checker can be invaluable in assessing and adjusting color combinations for optimal accessibility.
