General Information About Ultramarine

The color #2105af, known as Ultramarine, is a deep and intense shade of blue that lies closer to the violet end of the spectrum. Its name originates from the Latin 'ultramarinus', meaning 'beyond the sea', as it was historically derived from the rare and expensive mineral lapis lazuli, imported from faraway lands. Ultramarine symbolizes depth, wisdom, and stability. In the RGB color model, #2105af is composed of 12.9% red, 2.0% green, and 68.6% blue. In the CMYK color model, it consists of 81% cyan, 97% magenta, 0% yellow, and 31% black. This color is often associated with trust, loyalty, and authority, making it a popular choice for branding and design elements where conveying these qualities is important.

The hex color #2105af, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 4% means that text rendered in this color against a white background will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. To ensure accessibility, it's crucial to pair #2105af with very light colors for text or interface elements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Consider using a color contrast checker to verify compliance. Additionally, avoid relying solely on color to convey information; use supplementary cues like text labels or icons. When using this color for interactive elements, provide sufficient visual cues to indicate focus and hover states to aid keyboard navigation.
