This particular hue falls within the broader blue color family but distinguishes itself with a unique blend of cyan and deeper blue tones. Historically, cerulean pigments were derived from cerulean blue chloride, a synthetic compound first introduced in the 19th century. The name 'cerulean' itself originates from the Latin word 'caeruleus,' meaning 'dark blue' or 'sky-blue'. In color psychology, blue is often associated with trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven.

Its versatility allows it to be used effectively in both digital and print media, offering a visually appealing and emotionally resonant color option.
The color #2D4CB9, a shade of cerulean blue, presents some accessibility challenges. Its luminance value is relatively low, which means it may not provide sufficient contrast when used as text against a white or very light background. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. A contrast ratio of at least 4.5:1 is recommended for standard text, and 3:1 for large text. Using tools to evaluate the contrast ratio between #2D4CB9 and the background color is highly recommended. If the contrast is insufficient, consider using a lighter shade of blue or a completely different color for the background. Alternatively, using #2D4CB9 for larger graphical elements or as an accent color might be more appropriate to mitigate accessibility concerns. Ensure that any interactive elements using this color have sufficient visual cues to indicate their interactive state.
