This composition results in a deep, rich blue hue that evokes feelings of calmness, stability, and trust. Ultramarine's wavelength falls within the blue region of the visible spectrum. Historically, ultramarine pigment was derived from the semi-precious stone lapis lazuli, making it highly valued and expensive, often reserved for painting the robes of important figures in religious art.

In color psychology, ultramarine is associated with intelligence, authority, and sophistication.

The color #030794, a deep ultramarine, presents specific accessibility considerations for web developers. Due to its low luminance, it is crucial to ensure sufficient contrast when used as either text or background color. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Using #030794 for text on a white background, or vice versa, would likely fail these contrast tests. Therefore, it's recommended to pair this color with lighter shades or tints to achieve adequate contrast. Tools like WebAIM's contrast checker can be used to verify compliance. Moreover, avoid using color alone to convey important information, as colorblind users might miss it. Supplement color cues with text labels or icons to ensure inclusivity.
