In color psychology, blue is generally linked to trustworthiness, reliability, and intelligence, making Cerulean Blue a popular choice for corporate branding and web design. The name "Cerulean" comes from the Latin word "caeruleus," meaning "dark blue" or "sky blue." This hue sits between azure and sapphire on the color spectrum and is often used to represent the sky or the sea.

The hex color #2E54B8, also known as Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white is approximately 4.6:1, which meets WCAG AA standards for normal text but falls short of AAA standards. When used as a background color, ensure that text is appropriately sized (14pt bold or 18pt regular) to maintain readability. Against black, the contrast is significantly lower, necessitating careful consideration of text size and weight. Providing sufficient contrast helps users with visual impairments, including those with low vision or color blindness, to perceive content effectively. Designers should use contrast checkers to validate color combinations and consider alternative color pairings if necessary to enhance inclusivity. Remember that color alone should never be used to convey important information; always supplement with text or other visual cues.
