General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1B149F, 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 made from ground lapis lazuli, making it one of the most expensive pigments. Nowadays, synthetic ultramarine is widely available, but it still retains its association with luxury and artistic expression. In color theory, ultramarine is considered a cool color and is often associated with calmness, depth, and stability. It is commonly used in art, design, and branding to evoke feelings of trust and sophistication. The color has a strong presence without being overly aggressive, making it a versatile choice for a variety of applications.

The color #1B149F, also known as Ultramarine, presents some accessibility challenges, particularly in text-based applications. Its dark hue results in a low contrast ratio against standard light backgrounds, potentially making it difficult for users with visual impairments to read text rendered in this color. To improve accessibility, consider pairing #1B149F with light-colored text or using it for large graphical elements where readability is less critical. Adhering to WCAG (Web Content Accessibility Guidelines) contrast ratio recommendations is crucial. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is generally recommended. Tools are available to check color contrast ratios to ensure compliance. Alternatively, consider using a lighter shade of blue or a different color altogether to enhance readability for all users. When using #1B149F for interactive elements, providing clear visual cues beyond color is essential, such as underlines for links or icons for buttons.
