General Information about Ultramarine
The hex color #2307ad, also known as Ultramarine, is a deep, saturated shade of blue with a hint of violet. It resides in the blue-violet region of the color spectrum. In the RGB color model, it is composed of 13.73% red, 2.75% green, and 67.84% blue. In the CMYK color model, which is often used for printing, it is composed of 80% cyan, 96% magenta, 0% yellow, and 32% black. Ultramarine historically refers to a pigment derived from lapis lazuli, a semi-precious stone. The name means "beyond the sea" because the stone was imported into Europe from Asia by sea. Synthetic ultramarine, a chemically identical pigment, is now widely available and more affordable than the original. The color is associated with royalty, depth, trust, and intelligence.
The hex color #2307ad, also known as Ultramarine, presents some accessibility challenges, especially when used as a background color for text. Due to its dark nature, a light text color (white or a very light shade of gray) is essential to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text (14 points and bold or larger, or 18 points or larger). Using a color contrast checker is highly recommended to verify compliance. When using #2307ad for interactive elements like buttons or links, make sure the hover, focus, and active states also provide enough contrast to be easily discernible by users with visual impairments. Also avoid using this color as the sole means of conveying important information, as users with color blindness may not be able to perceive it properly.
