#130AAA

General Information about Ultramarine

The hexadecimal color #130AAA, also known as Ultramarine, is a deep and saturated shade of blue. It belongs to the blue color family and is characterized by its strong, almost violet undertones. In the RGB color model, it is composed of 7.45% red, 0% green, and 66.67% blue. Its CMYK values are 90% cyan, 100% magenta, 0% yellow, and 33% black. Ultramarine's name derives from the pigment originally made by grinding lapis lazuli, a semi-precious stone. Historically, this pigment was highly valued for its vibrancy and durability, making it a popular choice among artists. Today, synthetic ultramarine pigments provide a more accessible and affordable alternative, while maintaining the color's distinctive and captivating appearance.

The color #130AAA, also known as Ultramarine, presents some accessibility challenges, especially in text-based contexts. Its low lightness value (relative luminance around 0.02) means that it requires very light text on top to meet WCAG standards for contrast ratios. For standard text sizes (14pt/18px and below), a contrast ratio of at least 4.5:1 is needed, while larger text (18pt/24px and above) requires a 3:1 ratio. Using #130AAA as a background color mandates careful selection of foreground text colors, leaning towards white or very light shades of grey. When used for interactive elements like buttons, ensure sufficient contrast in all states (default, hover, focus, and active) to cater to users with visual impairments. Also, avoid using it as the sole indicator for conveying information, as colorblind users might not perceive it accurately. Always supplement color cues with text labels or other visual indicators.
