Cerulean Blue, represented by the hexadecimal color code #2E3FDD, is a vibrant and captivating shade of blue. It is positioned in the blue region of the color spectrum and is often associated with feelings of calmness, serenity, and inspiration. The color's name originates from the Latin word 'caeruleus,' which means 'dark blue,' 'blue-green,' or 'sky blue.' In terms of color theory, Cerulean Blue is a tertiary color, meaning it is created by mixing a primary color (blue) with a secondary color (green or violet, depending on the desired hue). This particular shade exhibits a strong blue component, making it a versatile choice for various design applications. Its unique characteristics make it stand out amongst other blues.

The color #2E3FDD, also known as Cerulean Blue, presents some accessibility challenges, particularly regarding text contrast. When using this color as a background, it is crucial to select foreground text colors that provide sufficient contrast to ensure readability for all users, including those with visual impairments. White text generally works well against Cerulean Blue, but it's essential to test the contrast ratio using a tool like the WebAIM Contrast Checker to verify compliance with WCAG guidelines. The color's luminance should be considered, and adjustments may be needed, such as darkening the background slightly or lightening the text, to achieve the recommended contrast levels. Additionally, avoid using Cerulean Blue for essential visual elements like links or buttons without clear text labels and sufficient contrast, as this can create usability barriers.
