General Information about Cerulean Blue

In the RGB color model, #204AB6 is composed of 12.55% red, 29.02% green, and 71.37% blue. This specific combination creates a color that is often associated with tranquility, stability, and calmness. It is widely used in various fields, including art, design, and marketing, to evoke feelings of trust, peace, and serenity. Cerulean Blue's versatility makes it a popular choice for backgrounds, accents, and branding elements.

The color #204AB6, also known as Cerulean Blue, presents some accessibility challenges, particularly in text-based applications. Its relatively low luminance value means that it requires careful consideration of contrast ratios against background colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background to ensure readability for users with visual impairments. When using #204AB6 for text, pairing it with a light color such as white (#FFFFFF) or a very pale yellow would be advisable. Conversely, using it as a background color necessitates a dark foreground color like black (#000000) or a dark gray to meet accessibility standards. Tools and online resources are available to check color contrast ratios and ensure compliance with accessibility guidelines, promoting inclusive design practices.
