About Ultramarine

Ultramarine, represented by the hexadecimal color code #121689, is a deep, vivid blue pigment that has been prized for centuries. Derived from the Latin 'ultramarinus', meaning 'beyond the sea', it was originally made from the semi-precious stone lapis lazuli, imported from Afghanistan. This made it an incredibly expensive pigment, reserved for only the most important commissions, such as paintings of the Virgin Mary. Today, synthetic ultramarine is widely available, making it a more accessible color for various applications. Ultramarine blue is known for its intense hue and excellent lightfastness, making it a popular choice in art, design, and manufacturing. It represents calmness and serenity, making it ideal for many industries.

The color #121689, a deep shade of ultramarine, presents some accessibility challenges, particularly in web design. Its low luminance value means that text rendered in this color on a white background (or vice versa) may not meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements for readability. To ensure accessibility, it's crucial to pair #121689 with a very light color for text or other important visual elements. A contrast checker tool can help determine if the contrast ratio is sufficient. Consider using larger font sizes or adding a text shadow or outline to improve readability. In cases where sufficient contrast cannot be achieved, it may be necessary to explore alternative, lighter shades of blue or other colors that offer better contrast while still maintaining the desired aesthetic. It is very important to consider accessibility so that everyone can use the website without issues.
