About Ultramarine

Ultramarine (#2001B2) is a deep blue color with a strong presence, known for its historical significance and use in fine art. The name 'Ultramarine' originates from the Latin 'ultramarinus', meaning 'beyond the sea,' as it was originally imported from mines in Afghanistan. The pigment was historically made from lapis lazuli, making it one of the most expensive and highly valued pigments. Today, synthetic ultramarine is widely available, retaining the color's characteristic brilliance at a fraction of the cost. In color theory, ultramarine is considered a cool color, evoking feelings of calmness, trust, and authority. Its hexadecimal value of #2001B2 indicates the combination of red, green, and blue light needed to produce this specific shade on digital displays.

The hex color #2001B2, also known as Ultramarine, presents specific accessibility considerations for web design. When using this color for text, it's essential to ensure sufficient contrast against the background. Due to its dark nature, pairing it with light colors such as white (#FFFFFF) or very pale yellow (#FFFFE0) is crucial to meet WCAG (Web Content Accessibility Guidelines) standards for readability. Using it for interactive elements like buttons or links requires careful consideration of focus states, where a contrasting outline or background change is necessary to indicate selection. Additionally, avoid using #2001B2 as the sole indicator of important information, as users with color vision deficiencies might struggle to distinguish it. Providing alternative visual cues such as text labels or icons can greatly improve accessibility for all users.
