About Cerulean Blue (#1F4AC7)

Cerulean Blue, represented by the hex code #1F4AC7, is a captivating shade of blue that evokes feelings of tranquility and serenity. It is a versatile color that finds applications in various fields, including web design, fashion, and interior decoration. Cerulean Blue is a tertiary color, meaning it is created by mixing a primary color (blue) with a secondary color (in this case, a mix of green and red resulting in violet). The color is often associated with the sky and the ocean, making it a popular choice for creating calming and peaceful environments. Its unique blend of blue with a hint of cerulean sets it apart from other shades of blue, making it a distinctive and memorable color.

The hex color #1F4AC7, also known as Cerulean Blue, presents some accessibility challenges for web developers. Due to its relatively low luminance, text rendered in this color may be difficult for users with visual impairments to read, especially against a white or light-colored background. To ensure accessibility, it's crucial to consider the contrast ratio between the text color and the background color. A contrast ratio of at least 4.5:1 is recommended for normal text, and 3:1 for large text, according to WCAG guidelines. Using a color contrast checker tool can help determine if the contrast ratio meets accessibility standards. If the contrast is insufficient, consider using a lighter shade of blue or a darker background color to improve readability and ensure that the content is accessible to a wider audience, including those with low vision or color blindness.
