About Ultramarine (#0C118C)

The hex color #0c118c, commonly known as Ultramarine, is a deep and rich shade of blue, evoking feelings of depth, mystery, and sophistication. In the RGB color model, it is composed of 4.71% red, 6.67% green, and 54.9% blue. The color's significant blue component gives it a strong association with the sea and sky, often symbolizing tranquility, stability, and wisdom. Historically, Ultramarine was derived from the precious mineral lapis lazuli, making it a highly valued pigment, particularly during the Renaissance. Its rarity and cost contributed to its association with royalty and spirituality. Today, synthetic versions of Ultramarine are widely available, making it accessible for various applications in art, design, and fashion. In color psychology, Ultramarine is often linked to intelligence, trust, and efficiency. It is a popular choice for branding and marketing materials, particularly for companies that wish to convey a sense of professionalism and reliability.

The hex color #0c118c, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of approximately 1% means that text rendered in this color against a white background will have a very poor contrast ratio. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to meet AA compliance. Ultramarine falls far short of these benchmarks. Using this color for essential textual information without careful consideration of contrast can exclude a substantial portion of users. When using this color, ensure that foreground elements have a sufficiently high contrast ratio to meet accessibility standards. This might involve using a very light color, such as white or a light yellow, for text or interactive elements placed against an Ultramarine background. Furthermore, avoid relying solely on color to convey meaning, as users with color vision deficiencies may struggle to distinguish Ultramarine from other dark shades.
