#0C0593

General Information about Ultramarine

The hex color #0C0593, also known as Ultramarine, is a deep, saturated blue. In the RGB color model, it is composed of 4.71% red, 2.75% green, and 57.65% blue. This combination results in a color that is perceived as authoritative, trustworthy, and intellectual. Ultramarine, historically derived from the precious mineral lapis lazuli, carries a sense of luxury and sophistication. It's often associated with depth, stability, and confidence. The color is commonly used in corporate branding to convey reliability and professionalism. In art, ultramarine has been a prized pigment since the Middle Ages, known for its vibrant and lasting hue. Today, synthetic versions make it more accessible, but its rich history and association with high quality endure, making it a popular choice across various design fields.

The color #0C0593, a deep ultramarine, presents accessibility challenges, particularly for users with visual impairments. Its low luminance of approximately 2% means it offers very little contrast against common background colors like white, which has a luminance around 100%. According to WCAG guidelines, sufficient contrast is essential for readability. For standard text (size 14 regular or 12 bold), a contrast ratio of at least 4.5:1 is recommended. For large text (size 18 regular or 14 bold), the minimum ratio is 3:1. Using #0C0593 for text on a white background would fall far short of these recommendations, making it difficult for many users to read. To improve accessibility, pair #0C0593 with very light colors like #FFFFFF or #F0F0F0 to achieve the required contrast ratio. Tools like contrast checkers can help measure and adjust the color combinations to meet accessibility standards, ensuring content is perceivable and usable by everyone.
