Its richness and intensity make it a popular choice for designs aiming to convey a sense of luxury or elegance. Historically, blue pigments were derived from natural sources such as lapis lazuli, a semi-precious stone found in Persia (modern-day Iran), which may have contributed to the color's name.

The color #281BB5, also known as Persian Blue, presents some accessibility challenges, particularly in text-based contexts. Its relatively low luminance of approximately 9% necessitates careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background for Level AA compliance. When used as text, #281BB5 demands a very light background to meet these standards. White (#FFFFFF) is a suitable option, providing sufficient contrast. However, avoid pairing it with darker backgrounds, as readability will be severely compromised for users with visual impairments. For non-text elements such as icons or graphical components, a contrast ratio of 3:1 is sufficient. In user interface design, consider providing alternative themes or color palettes that offer better contrast options, allowing users to customize their experience based on individual needs. Color blindness simulations can help identify potential issues for individuals with different types of color vision deficiencies. Also make sure to check the color ratios with an automated contrast checker tool.
