This color is often associated with royalty, intelligence, and tranquility. In the RGB color model, #131488 is composed of 7.45% red, 7.84% green, and 53.33% blue.

Historically, Ultramarine was derived from the rare and expensive mineral lapis lazuli, making it a prized pigment in Renaissance paintings.

Its distinctive shade makes it a powerful tool for conveying specific moods and messages in visual communication.

The hex color #131488, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark shade results in a low luminance value, creating insufficient contrast against lighter backgrounds commonly used for text and interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Ultramarine often fails to meet these standards when paired with typical light backgrounds like white or light gray. To improve accessibility, consider using Ultramarine with very light text colors like white (#FFFFFF) or very light yellow. Or use Ultramarine for decorative elements where the lack of contrast won't hinder usability. Thoroughly test color combinations with accessibility tools to ensure compliance with WCAG guidelines and to provide a usable experience for all users, including those with low vision or color blindness.
