General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0C178F, is a deep, saturated blue color that evokes feelings of serenity, depth, and sophistication. It falls within the blue color family and is characterized by its strong, almost regal presence. In the RGB color model, it is composed of 4.71% red, 9.02% green, and 56.08% blue. Ultramarine's name originates from the Latin 'ultramarinus', meaning 'beyond the sea', as the pigment was originally derived from lapis lazuli imported from Asia. Historically, it was a highly valued pigment used in paintings, particularly during the Renaissance period. Today, synthetic ultramarine is widely available, making it more accessible for various applications. The color is often associated with royalty, wisdom, and spirituality.

The color #0C178F, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its very dark hue results in low contrast against typical light backgrounds, making text and other visual elements difficult to discern. According to WCAG guidelines, sufficient contrast ratios are crucial for readability and usability. To improve accessibility, consider using this color sparingly and pairing it with very light backgrounds to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Alternatively, use a lighter tint of Ultramarine or a completely different, lighter color altogether. Providing alternative text descriptions for images and icons using this color is also beneficial. Testing the color scheme with accessibility evaluation tools and user testing with individuals with visual impairments can help identify and address potential accessibility issues.
