General Information about Ultramarine

The hex color #121989, also known as Ultramarine, is a deep shade of blue. It's a color often associated with royalty, depth, and intelligence. In the RGB color model, it is composed of 7.06% red, 9.8% green, and 53.73% blue. The name 'Ultramarine' originates from the Latin 'ultramarinus', meaning 'beyond the sea', as the pigment was originally imported from Asia. It is historically significant, having been used in paintings and illuminated manuscripts. Its modern applications range from web design to fashion, though careful consideration must be given to its use due to accessibility concerns. The color emits a sense of sophistication and elegance when used effectively.

The color #121989, a deep ultramarine, presents significant accessibility challenges, especially in text applications. Its low luminance value (relative darkness) necessitates very light text colors for sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using white (#FFFFFF) or very light shades of gray is crucial to meet these standards. Tools like contrast checkers can help ensure compliance. Also, avoid using this color for critical interactive elements if you cannot guarantee sufficient contrast. Providing alternative color schemes can improve accessibility for users with visual impairments. Non-text elements should have a contrast ratio of 3:1 with adjacent colors. Proper color choice is paramount for ensuring an inclusive web experience.
