Ultramarine
General Information about #1F0B90
The hexadecimal color #1F0B90 is a deep, saturated shade of blue, often referred to as Ultramarine. It resides in the blue region of the color spectrum and is characterized by its rich and intense hue. The color is created by combining relatively low amounts of red (1F) and green (0B) with a high amount of blue (90) in the RGB color model. In the CMYK color model, it translates to a high percentage of cyan and magenta, with a smaller percentage of yellow. Ultramarine traditionally refers to a pigment derived from lapis lazuli, a semi-precious stone, making it historically a very valuable and sought-after color. It is often associated with royalty, spirituality, and depth.
The hex color #1F0B90, a deep ultramarine, presents considerable accessibility challenges. Its low luminance value (darkness) means that it offers very little contrast when used against common background colors like white. This lack of contrast can make text or interactive elements difficult, if not impossible, for users with visual impairments to discern. To ensure accessibility, this color should only be used with very light colors, such as white (#FFFFFF) or very light yellows. It's best practice to test color combinations using WCAG contrast ratio guidelines. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, to comply with WCAG AA standards. If that ratio is not met, consider using a lighter hue or using the color for decorative elements only. Always test with assistive technologies to ensure optimal usability.

When used in backgrounds, it evokes feelings of trust and stability, making it suitable for financial or corporate websites. However, care must be taken to ensure sufficient contrast with text and other foreground elements to meet accessibility standards. Furthermore, consider using this color in combination with lighter shades of blue or white to balance the intensity and create a visually pleasing interface.

It's a color that exudes confidence and sophistication. Alternatively, smaller elements like scarves, ties, or handbags in this color can add a touch of elegance to an outfit without being overwhelming. Consider using ultramarine in evening wear, or in professional settings to project authority.

It works well in bedrooms or living rooms, especially when paired with lighter colors to prevent the space from feeling too dark. It is often used as an accent wall, creating a dramatic focal point. Consider this color in combination with metallic accents like gold or silver to enhance the luxurious feel. Ultramarine can be incorporated through furniture, textiles, or artwork, adding a pop of color without overwhelming the space.
