General Information

It belongs to the blue color family and is often associated with the sky and sea. In color psychology, blue is known for its calming effects and is frequently used in corporate branding to convey reliability and professionalism. Cerulean Blue combines the steadfastness of blue with a slight vibrancy, making it more approachable than darker shades. Its use in design can create a sense of peace and order, promoting a focused and relaxed atmosphere. The color is also associated with intelligence, efficiency, and communication, making it a popular choice for various applications.

The color #315EB5, a shade of cerulean blue, presents moderate accessibility challenges. Its contrast ratio against white text is approximately 3.5:1, which is below the WCAG's minimum recommendation of 4.5:1 for normal text. This means users with moderate visual impairments may find it difficult to read text on a white background. To improve accessibility, consider using a lighter text color like white or off-white, or darkening the blue shade. When paired with black text, the contrast is insufficient. Tools like contrast checkers can help evaluate different color combinations. Non-text elements like icons and graphics require a minimum contrast ratio of 3:1 to be discernible. Therefore, #315EB5 should be used with caution for interactive elements. Careful consideration of color choices ensures usability for individuals with varying visual abilities, promoting inclusivity.
