General Information about Ultramarine (#010D9A)

Ultramarine, represented by the hexadecimal color code #010D9A, is a deep, intense shade of blue. It is a color that evokes feelings of calmness, stability, and sophistication. The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the original pigment was derived from lapis lazuli imported from distant lands, primarily Afghanistan. This historical context lends the color an aura of rarity and prestige. In the RGB color model, Ultramarine consists of 0.4% red, 5.1% green, and 60.4% blue. Its high blue component contributes significantly to its characteristic deep blue appearance. Due to its strong blue saturation and minimal red and green components, Ultramarine leans towards the cooler end of the color spectrum. This makes it ideal for design applications requiring conveying trust and professionalism.

The hex color #010D9A, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely dark hue results in very low contrast against lighter backgrounds, making text and other visual elements difficult to discern. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine often fails to meet these standards when paired with common background colors like white or light gray. To improve accessibility, it is advisable to use Ultramarine sparingly, primarily for decorative elements or backgrounds, and to ensure that any text or interactive elements placed on it have sufficient contrast. Pairing it with very light shades of yellow, orange, or even a carefully chosen light gray can help achieve an acceptable contrast ratio. Also, providing alternative text descriptions for images and other non-text elements is crucial for users relying on screen readers.
