Ultramarine
General Information about Ultramarine
The color #170D8E, commonly known as Ultramarine, is a deep and intense shade of blue. It's located in the blue region of the color spectrum and carries a sense of depth and sophistication. This color is created by blending small amount of red and green light with a dominant amount of blue light. Ultramarine blue has a rich history, derived from the Latin "ultramarinus," meaning "beyond the sea," as it was originally imported from mines in Afghanistan. It was highly prized and used extensively in Renaissance paintings. The pigment was made from ground lapis lazuli. In modern color theory, #170D8E represents trust, stability, and wisdom, making it a popular choice in various branding and design applications.
The hex color #170D8E, a deep ultramarine, presents several accessibility considerations. Its high darkness value results in a strong contrast against lighter backgrounds, making it suitable for text and UI elements when paired appropriately. However, using it on dark backgrounds or with similarly dark colors can create insufficient contrast, hindering readability and usability for users with visual impairments. WCAG guidelines recommend a contrast ratio of at least 4.5:1 for standard text and 3:1 for large text. Therefore, careful evaluation with contrast checkers is crucial before implementation. Also, avoid using this color as the sole indicator for interactive elements, as users with color blindness may not perceive the difference. Providing additional cues like underlines or icons ensures inclusivity.
