General Information about Ultramarine

Ultramarine, represented by the hex code #0A0398, is a deep blue color with a rich history. The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from mines in Afghanistan by sea. Historically, it was derived from the gemstone Lapis Lazuli and was highly valued, often more expensive than gold, making it a color reserved for royalty and religious figures. Its usage can be traced back to medieval paintings and illuminated manuscripts. Today, synthetic versions of Ultramarine are widely available, retaining the color's characteristic depth and brilliance. In color theory, Ultramarine is considered a cool color, often associated with feelings of calmness, stability, and intellect. Its intense hue makes it suitable for various applications across art, design, and fashion.

The hex color #0A0398, also known as Ultramarine, presents some accessibility challenges, especially regarding color contrast. When used as a background color, it is crucial to pair it with a light text color to ensure readability. White or very light shades of yellow and green would be suitable choices. Conversely, using dark text colors will make the text nearly impossible to read for users with visual impairments. It's essential to check the contrast ratio using online tools to meet WCAG (Web Content Accessibility Guidelines) standards, aiming for a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Also, avoid using this color as the sole indicator for interactive elements; supplement it with text labels or icons to provide additional cues for users with color blindness. Considering these factors can significantly improve the accessibility of designs incorporating #0A0398.
