About Ultramarine

The hex color #0A0197, commonly known as Ultramarine, is a deep and intense shade of blue. It sits towards the violet end of the blue spectrum and evokes feelings of depth, stability, and sophistication. Historically, ultramarine was derived from the precious stone lapis lazuli, making it a highly valued pigment, especially in Renaissance art. The name "ultramarine" literally means "beyond the sea," reflecting its origin from overseas. Today, synthetic ultramarine is widely available, retaining the same vivid color while being more accessible and affordable. This color is often associated with royalty, wisdom, and tranquility.

The hex color #0A0197, a deep ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance contrast against white backgrounds makes text and interactive elements difficult to read. Web developers should avoid using this color for text or crucial interface components unless paired with a very light background color to ensure sufficient contrast, adhering to WCAG guidelines. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Consider using color contrast analyzers to verify compliance. Providing alternative, high-contrast themes or allowing users to customize colors can greatly enhance accessibility. It's also beneficial to avoid relying solely on color to convey information; use supplementary cues like icons or text labels.
