#180398

General Information about Ultramarine

Ultramarine, represented by the hex code #180398, is a deep and intense shade of blue that has been prized for centuries. Historically, it was derived from the mineral lapis lazuli, making it one of the most expensive and sought-after pigments. Its name, meaning "beyond the sea," reflects its origin as a pigment imported from distant lands. In modern color theory, Ultramarine is often associated with qualities such as royalty, wisdom, and tranquility. It is a popular choice in art, design, and fashion for its ability to convey both depth and sophistication. Due to its strong saturation, it is often used sparingly to create emphasis and visual interest. It is a cool color and is best complemented with warm colors.

The hex color #180398, also known as Ultramarine, presents significant accessibility challenges, especially in web design. Its dark hue results in very low contrast when paired with lighter text, potentially making content illegible for users with visual impairments. Following WCAG (Web Content Accessibility Guidelines), a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine struggles to meet these ratios with standard light foreground colors like white or light gray. To improve accessibility, consider using lighter shades of blues or vibrant yellows as the background color. Also, providing alternative text descriptions for images and interactive elements that use this color ensures that users with screen readers can still understand the content. Careful consideration is crucial when implementing this color in designs to avoid excluding users and maintain an inclusive experience.
