It's located in the blue-violet region of the color spectrum and is often associated with feelings of calmness, serenity, and stability. In terms of color theory, #2C51BA is created by mixing red, green, and blue light, with blue being the dominant component. This particular shade of cerulean blue evokes a sense of trust, confidence, and intelligence, making it a popular choice for corporate branding, web design, and even interior decor. Its versatile nature allows it to be used in various contexts, ranging from professional to creative. In branding it is often used to signal reliability and trustworthiness.

The hex color #2C51BA, a shade of cerulean blue, presents moderate accessibility challenges. Its contrast ratio against pure white (#FFFFFF) is approximately 2.8:1, which falls short of the WCAG's minimum recommendation of 4.5:1 for normal text and 3:1 for large text. Therefore, using #2C51BA directly on a white background for body text is not advisable. To improve accessibility, consider using it for larger text elements (headings, titles) or pairing it with darker shades of blue or black for better contrast. When used for interactive elements like buttons or links, ensure that sufficient visual cues, such as outlines or underlines, are present to distinguish them from surrounding text. Testing with accessibility tools and user feedback is essential to ensure an inclusive user experience.
