#130C8F

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #130C8F, is a deep and intense shade of blue. It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from regions beyond the sea, primarily from Afghanistan, where lapis lazuli, the source of natural ultramarine pigment, was mined. In color theory, ultramarine is considered a cool color, associated with feelings of calmness, depth, and stability. It is often used to convey a sense of trust, intelligence, and authority. The RGB values for #130C8F are R:19, G:12, B:143, indicating a strong dominance of blue. It is relatively dark, with a low luminance, giving it a sophisticated and mysterious appeal. Ultramarine has a long history in art, particularly during the Renaissance, where it was highly prized for its vibrant color and permanence.

The color #130C8F, a deep ultramarine, presents significant accessibility challenges. Its low luminance of only 3% means that text rendered in this color on a white background, or vice versa, will fail WCAG's contrast requirements by a large margin. The contrast ratio is approximately 5.4:1, far below the recommended 4.5:1 for normal text and 3:1 for large text. To ensure readability and inclusivity, especially for users with visual impairments, it is essential to pair this color with very light shades of yellow or white for text, or use it sparingly for decorative elements. Avoid using it for important information or interactive components without careful contrast adjustments. Consider adding a darker outline to light text on an ultramarine background to enhance readability. Tools are available to check color contrast ratios and simulate how colors appear to users with different types of color blindness, and they should be integrated into the design process when using this color.
