General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #150299, is a deep and intense shade of blue. Historically, the term 'ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally derived from the precious gemstone lapis lazuli, imported from distant lands, primarily Afghanistan. This color has been highly valued throughout history, particularly in art, where it was used by Renaissance painters for its rich and vibrant hue. In the RGB color model, #150299 is composed of 8.24% red, 0.78% green, and 60% blue. This high concentration of blue gives the color its characteristic deep blue appearance. The color evokes feelings of calmness and authority, but also can be seen as sadness.

The hex color #150299, a deep shade of ultramarine, presents several accessibility considerations for web design. Its low lightness value (around 8%) means that text rendered in this color requires very light foreground colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Therefore, using white (#FFFFFF) or very light shades of gray as the text color is crucial. Furthermore, avoid using this color for interactive elements or links without clear visual cues, as users with visual impairments might struggle to identify them. It is vital to test the color combination with accessibility tools to ensure compliance and optimal user experience for all users, including those with color vision deficiencies or low vision. Consider providing alternative color schemes for users who need them.
