It is a popular choice for corporate branding, website design, and various other applications where a sense of reliability and professionalism is desired. This color has a rich history, deriving its name from the Latin word 'caeruleus', which means 'sky blue' or 'sea blue'. Its widespread use in art and design stems from its ability to evoke feelings of peace and tranquility.
The hex color #2D55B9, a shade of cerulean blue, presents moderate accessibility challenges. Its contrast ratio against white text is approximately 3.7:1, which falls short of the WCAG AA standard of 4.5:1 for normal-sized text. To ensure readability for users with visual impairments, consider using a darker shade of text or a lighter background color. For larger text (14pt bold or 18pt regular), the contrast ratio meets the WCAG AA requirement of 3:1. However, for optimal accessibility across all text sizes, it's advisable to pair this cerulean blue with high-contrast colors. Black text on this background offers sufficient contrast and is recommended. When used as a background for interactive elements, make sure to test and adjust the color to meet the minimum contrast ratios for both text and non-text contrast.
