Cerulean Blue
General Information about Cerulean Blue
The hex color #1C4ACA, commonly known as Cerulean Blue, is a shade of blue that sits comfortably within the cyan-blue range of the color spectrum. This color is created by combining a specific ratio of red, green, and blue light, with red at 11.0%, green at 28.2%, and blue at 80.0%. In the RGB color model, these percentages translate to the values 28, 74, and 202, respectively. Cerulean Blue is often associated with feelings of calmness, serenity, and stability. It evokes imagery of the ocean and sky, making it a popular choice for designs aiming to create a sense of peace and tranquility. Its versatility allows it to be utilized in a variety of applications, from web design to fashion, each leveraging its unique psychological impact.
The hex color #1C4ACA, also known as Cerulean Blue, presents some accessibility challenges, particularly when used as a background or text color. Its relatively low luminance contrast against both white and black backgrounds requires careful consideration. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. For text, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. When using #1C4ACA for text, pair it with very light colors like white (#FFFFFF) or very dark colors like black (#000000) to achieve adequate contrast. Tools like contrast checkers can help assess compliance. If used as a background, ensure foreground elements provide sufficient contrast. Additionally, avoid relying solely on color to convey information, as colorblind users may struggle to distinguish it. Using supplementary cues like text labels or icons will improve usability for all users.

Web Design
In web design, Cerulean Blue can be used to create a sense of trust and security, often utilized in finance and banking websites. It's suitable for headers, navigation bars, and call-to-action buttons. When paired with white or light gray, it presents a clean and professional look. However, its use should be balanced, as excessive application can appear overwhelming. Consider using it strategically to highlight important elements and guide user attention. In user interface (UI) design, Cerulean Blue can serve as an accent color for icons and interactive components. It can also be used to indicate states such as active or selected, providing visual feedback to users.
Interior Design and Fashion
In interior design, Cerulean Blue can evoke feelings of calmness and serenity, making it appropriate for bedrooms and bathrooms. It can be used as an accent wall color or in decorative elements like pillows and curtains. Pair it with neutral tones like beige or gray to create a balanced and relaxing atmosphere. Avoid using it in excessively dark or small rooms, as it can make the space feel even smaller. In fashion, Cerulean Blue is often seen in casual wear such as shirts and dresses. It can also be used as an accent color in accessories like scarves and handbags. It complements well with other cool colors like green and purple, as well as neutral colors like white and black.
Brand Identity
Cerulean Blue is useful to create a brand identity on web and printing media. Use it carefully to highlight the focus of your design. If used as a background, ensure foreground elements provide sufficient contrast. Additionally, avoid relying solely on color to convey information, as colorblind users may struggle to distinguish it. Using supplementary cues like text labels or icons will improve usability for all users.
