General Information about Ultramarine (#1D09AB)

The hex color code #1D09AB represents a shade of blue known as Ultramarine. It is a deep, vibrant color that sits between blue and violet on the color spectrum. In the RGB color model, it is composed of 11.4% red, 3.5% green, and 67.1% blue. The color is often associated with royalty, wisdom, and depth. Ultramarine has a rich history, originally derived from the rare and expensive mineral lapis lazuli. This made it highly prized by artists and was often reserved for depicting important figures or scenes. Today, it's widely available as a synthetic pigment but still retains its association with luxury and artistic expression. Because of its darker hue, it is not recommended to use it as a background color for big blocks of text.

The color #1D09AB, a deep shade of ultramarine, presents some accessibility challenges, especially when used as text against a white background. Its low luminance results in a contrast ratio that may not meet WCAG (Web Content Accessibility Guidelines) standards for text legibility. To improve accessibility, consider using this color for larger text elements or graphical elements, or pairing it with a very light color like #FFFFFF or #F0F0F0 for sufficient contrast. When using this color for interactive elements like buttons, ensure there's a clear visual cue on hover or focus to aid users with visual impairments. Also, avoid using it as the sole means of conveying important information, as users with color blindness may struggle to differentiate it from similar dark hues. Providing alternative visual cues, such as icons or text labels, can ensure information is accessible to everyone.
