Ultramarine has a long and storied history, originally derived from the rare and expensive mineral lapis lazuli. Because of its origin and the time needed to create the pigment, it was often used for paintings for commissioners with higher budget.

The color #1D12A2, also known as Ultramarine, presents some accessibility challenges, particularly in web design. Its dark hue results in a low contrast ratio when paired with lighter text colors like white or very pale shades. To ensure readability for all users, including those with visual impairments, it's essential to use sufficiently contrasting text colors, such as bright yellows or light greens. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using Ultramarine as a background, avoid pairing it with similarly dark colors, as this will make the text nearly impossible to read. Consider using a color contrast checker tool to verify that your color choices meet accessibility standards.
