About Ultramarine

Historically, ultramarine was derived from the precious stone lapis lazuli, making it a highly valued pigment, especially in Renaissance painting. The name 'ultramarine' literally means 'beyond the sea,' referring to its origin from stones imported into Europe from Asia. In the RGB color model, #16009B consists of 8.63% red, 0% green, and 61.18% blue. In the CMYK color model, it is composed of 86% cyan, 100% magenta, 0% yellow, and 39% black. This color is often associated with feelings of royalty, wisdom, and serenity.

The color #16009B, a deep ultramarine, presents several accessibility considerations for web development. Its dark hue results in high contrast against white text, generally meeting WCAG standards for readability. However, when paired with darker shades or busy backgrounds, readability can be compromised. Ensuring a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) is crucial. Additionally, avoid using this color as the sole indicator of interactive elements like links or buttons. Supplement it with underlines, icons, or text labels to aid users with color vision deficiencies. Thorough testing with accessibility tools and real users is recommended to validate sufficient contrast and clarity, especially for users with visual impairments.
