General Information About Ultramarine

Ultramarine, represented by the hexadecimal color code #2501B3, is a deep and rich shade of blue. Historically, Ultramarine was a pigment derived from the mineral lapis lazuli, making it one of the most expensive and highly valued colors in art. Its name literally means 'beyond the sea,' referring to its origin from overseas sources. In modern times, synthetic versions of Ultramarine are widely available, making it more accessible for various applications. The color is often associated with royalty, wisdom, and spirituality. In color psychology, deep blues like Ultramarine can evoke feelings of calmness, trust, and stability. It's often used in branding and design to convey a sense of reliability and professionalism. Due to its depth, Ultramarine can add a touch of elegance and sophistication to designs and visual media.

The color #2501B3, also known as Ultramarine, presents significant accessibility challenges. Its dark hue results in low contrast against light backgrounds, making text or interactive elements difficult to read 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. Ultramarine often fails to meet these standards, particularly when paired with common background colors like white or light gray. To improve accessibility, consider using Ultramarine sparingly for decorative elements or pairing it with very light or white text. Ensure sufficient contrast by using tools to measure the contrast ratio and making adjustments as needed. Furthermore, provide alternative visual cues, such as icons or labels, to ensure that information is conveyed effectively to all users, including those who may not be able to distinguish the color clearly.
