#1405AE

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1405AE, is a deep blue pigment historically derived from the mineral lapis lazuli. Its name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was imported into Europe from mines in Asia. Renowned for its intense and vibrant hue, ultramarine has been prized by artists throughout history, including Renaissance masters, for its exceptional colorfastness and brilliance. In modern applications, synthetic ultramarine is widely used in paints, plastics, cosmetics, and other products due to its stability and non-toxicity. This pigment is also used to offset yellow undertones in white materials, enhancing brightness. The hex code #1405AE signifies a color composed primarily of blue, with relatively low contributions from red and green, resulting in a deep, almost royal, blue shade.

The hex color #1405AE, also known as Ultramarine, presents specific accessibility challenges, particularly in text and user interface design. Its dark hue means it requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, text should have a contrast ratio of at least 4.5:1 against its background for normal text and 3:1 for large text. When using #1405AE for text, a very light color such as white or a very pale yellow is necessary to meet these standards. Similarly, when using it as a background color, text must be a light color. Failure to ensure adequate contrast can render content unreadable for many users, including those with low vision or color blindness. Therefore, designers and developers must rigorously test color combinations to guarantee accessibility.
