Ultramarine

#1A078B

General Information about Ultramarine (#1A078B)

The color #1A078B, commonly known as Ultramarine, is a deep shade of blue. Its origins trace back to the pigment derived from the precious mineral lapis lazuli. Revered throughout history, particularly during the Renaissance, it was highly prized by artists for its rich and vibrant hue, often reserved for depicting religious figures and royalty. Due to the high cost of lapis lazuli, ultramarine was once more expensive than gold. Nowadays, synthetic ultramarine is readily available, making it accessible for various applications. It is located in the blue spectral region, and provides a sense of calmness and stability. Its hexadecimal triplet is 1A, 07, and 8B, which represent the red, green, and blue intensities, respectively. In the RGB color space, this translates to a relatively low amount of red and green, and a high amount of blue, giving it the characteristic deep blue appearance.

The color #1A078B, a deep ultramarine, presents several accessibility considerations. Its low luminance necessitates high contrast ratios when used with text or other interactive elements. A light color, such as white or a pale yellow, should be used for text on a #1A078B background to ensure readability, meeting WCAG guidelines for contrast. Conversely, avoid pairing it with similar dark hues, as this will create insufficient contrast and hinder usability for individuals with visual impairments. When used as a background for interactive elements, ensure sufficient size and spacing for easy selection. The color can be perceived differently based on screen calibration, so testing across various devices is recommended to maintain consistent accessibility. Consider providing alternative visual cues in addition to color to convey information, especially for users who are colorblind.
