This color sits between blue and violet on the color spectrum and is known for its intensity and depth. In color theory, Ultramarine conveys feelings of trust, intelligence, and stability, making it a popular choice for branding and design in various industries, including technology and finance. Historically, ultramarine pigment was highly valued and expensive, often reserved for important artistic works.

It is created by combining different amounts of red, green and blue.

The hex color #121187, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates very light text colors to ensure readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) AA standards. Using color contrast analyzers is crucial to verify compliance. Due to its dark nature, this color may not be suitable for elements requiring high visibility, such as form fields or interactive buttons. Consider using it sparingly or pairing it with strategic color combinations to enhance accessibility and avoid excluding users with visual impairments. Careful consideration must be given to its impact on users with low vision or color blindness, who may struggle to distinguish elements against this dark background. Testing with different user profiles is advisable to ensure the design is inclusive.
