About Ultramarine

Ultramarine, represented by the hexadecimal color code #0D07AD, is a deep, vivid shade of blue. It derives its name from the pigment originally made from lapis lazuli, a semi-precious stone. Historically, ultramarine was highly prized, often more expensive than gold, and was reserved for important works of art, particularly in religious paintings. The color is characterized by its strong saturation and slight violet undertones. In the RGB color model, #0D07AD is composed of 5.1% red, 2.7% green, and 67.8% blue. This composition results in a color that is both striking and calming, evoking feelings of depth, tranquility, and sophistication. Its distinctive hue makes it a popular choice in various design applications.

The color #0D07AD, also known as Ultramarine, presents several accessibility considerations for web developers. Due to its low luminance, it is crucial to ensure sufficient contrast between text and background when using this color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #0D07AD as a background color requires light-colored text to meet these standards. Tools like contrast checkers can help verify compliance. Additionally, it's important to provide alternative visual cues besides color to convey information, as colorblind users may have difficulty distinguishing this color. Consider using icons, patterns, or text labels to enhance usability for all users. Keyboard focus indicators should also be clearly visible against this dark background to ensure keyboard navigation is accessible.
