General Information about Ultramarine (#150CA8)

The hex color #150CA8, also known as Ultramarine, is a deep, saturated blue hue. In the RGB color model, it is composed of 8.24% red, 4.71% green, and 65.88% blue. This signifies a strong dominance of blue, contributing to its characteristic depth and intensity. Ultramarine is historically significant, originally derived from the precious mineral lapis lazuli. This natural pigment was highly valued for its rich, vibrant color and was often used in Renaissance paintings. Today, synthetic versions of Ultramarine are widely available, making it more accessible for various applications. This color evokes feelings of serenity, trust, and stability, often associated with the ocean and the sky. It is commonly used in branding and design to convey a sense of reliability and professionalism.

The hex color #150CA8, also known as Ultramarine, presents accessibility challenges primarily due to its low lightness value. When used as a foreground color against a white background, it can result in insufficient contrast, making it difficult for users with visual impairments to read text or discern important visual elements. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. To improve accessibility, consider using a lighter background color or a lighter shade of blue for the foreground. Alternatively, using this color sparingly for purely decorative elements is also advisable. Implementing these adjustments ensures a more inclusive and user-friendly experience for all users, regardless of their visual abilities. Proper testing with accessibility tools is highly recommended.
