It is a color often associated with the sky and ocean, making it a popular choice in various fields like design, fashion, and art. The hex code specifies the combination of red, green, and blue light intensities that create this particular hue, with relatively low amounts of red and a balanced mix of green and blue.

Its moderate saturation and brightness also make it versatile for pairing with a wide range of other colors.

The color #305EB6, a shade of cerulean blue, presents some accessibility considerations, especially for web content. Its contrast ratio against white (#FFFFFF) is approximately 4.6:1, which meets the WCAG AA standard for normal text but falls short for larger text or user interface components. When using this color for text, consider increasing the font size or weight to ensure readability. Pairing it with lighter shades of yellow, beige, or even a very pale blue can enhance contrast and improve accessibility for users with visual impairments. Conversely, avoid using it with dark grays or blacks for text, as the contrast will be insufficient. Careful consideration of context and font size is crucial when using #305EB6 to create an inclusive and accessible user experience.
