General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #110DA7, is a deep blue hue known for its rich and intense character. It is classified as a cool color, often associated with tranquility, stability, and depth. In the RGB color model, #110DA7 consists of 6.67% red, 5.1% green, and 65.49% blue. The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from distant lands, primarily Afghanistan, where it was derived from the mineral lapis lazuli. Historically, it was a highly prized and expensive pigment used in fine art, particularly during the medieval and Renaissance periods. The color's association with royalty and divinity made it a symbol of luxury and reverence. Today, synthetic ultramarine is widely available and used in various applications, including paints, plastics, and cosmetics, maintaining its status as a valued and evocative color.

The hex color #110DA7, also known as Ultramarine, presents some accessibility challenges, primarily due to its deep, saturated hue. When used as a foreground color for text, it demands careful consideration of contrast ratios. To ensure readability for users with visual impairments, including those with low vision or color blindness, it's crucial to pair Ultramarine with a light background. White or very pale shades of yellow, green, or blue would be preferable. Tools like the WebAIM contrast checker can be used to verify that the contrast ratio meets WCAG (Web Content Accessibility Guidelines) standards, aiming for a minimum ratio of 4.5:1 for regular text and 3:1 for large text. Avoid using #110DA7 on similar dark backgrounds, or pairing it with other dark hues, as this reduces contrast and makes content difficult to read. Also, be mindful of the color's impact on users with cognitive disabilities, as highly saturated colors can sometimes cause distractions or visual stress. Consider providing alternative color schemes or styles to accommodate individual preferences and needs.
