General Information about Cerulean Blue

It is a popular color choice for conveying feelings of calmness, serenity, and trustworthiness. In the RGB color model, it consists of 16.47% red, 32.94% green, and 73.73% blue.

In branding and design, Cerulean Blue can be effectively used to establish a sense of reliability and professionalism. Its versatility allows it to be used in various applications, ranging from website design to marketing materials. Careful consideration should be given to its contrast with other colors to ensure readability and accessibility.
The hex color #2A54BC, also known as Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white is approximately 3.7:1, which falls short of the WCAG's recommended 4.5:1 for normal text. This means that text using this color on a white background might be difficult for users with visual impairments to read comfortably. To improve accessibility, consider using a darker shade of blue or a lighter background color to increase the contrast. For larger text (14pt bold/18pt regular), the contrast ratio of 3:1 is met. Additionally, avoid using this color as the sole indicator of important information, such as links or error messages. Providing alternative cues, like underlining links or using icons alongside text, can enhance usability for all users, including those with color vision deficiencies. Testing the color combination with accessibility evaluation tools is always recommended.
