General Information about Ultramarine

Ultramarine, represented by the hex code #190BA9, is a deep, vivid blue color that has been prized for centuries. Its name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally derived from the precious gemstone lapis lazuli, imported from distant lands. Historically, ultramarine pigment was incredibly expensive and highly valued, often reserved for use in paintings of religious or significant figures. Today, synthetic ultramarine is widely available, making this beautiful color accessible for various applications. In color theory, ultramarine is considered a cool color, often associated with feelings of tranquility, depth, and stability. Its rich tone makes it a popular choice in design and art, where it can add a sense of elegance and sophistication. It is also used in industrial applications.

The hex color #190BA9, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as a foreground color for text, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast. A dark blue like this can be difficult for users with low vision or color blindness to discern against darker backgrounds. Therefore, it is essential to use contrast checking tools to ensure readability. In user interface design, avoid pairing this color with other dark shades. Instead, consider using it sparingly for decorative elements or accents, where its vibrant hue can add visual interest without compromising accessibility. Always prioritize providing alternative visual cues, such as text labels or icons, to ensure that all users can understand the information being conveyed, regardless of their visual abilities. Proper use of ARIA attributes can also improve the experience for those using screen readers.
