General Information
The hexadecimal color #264CB0, also known as Cerulean Blue, is a captivating shade that resides in the blue color spectrum. It is created by mixing specific amounts of red, green, and blue light, with its RGB values being R:38, G:76, and B:176, respectively. The color's composition translates to a relatively low red and green presence and a prominent blue component, which gives it the cool, tranquil character. In the CMYK color model, which is typically used for printing, it consists of C:78, M:57, Y:0, and K:31.

Its name is derived from the Latin word 'caeruleus', meaning 'dark blue' or 'sky blue'.
The color #264CB0, also known as Cerulean Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value of approximately 0.11 makes it difficult to achieve sufficient contrast against lighter backgrounds, potentially violating WCAG (Web Content Accessibility Guidelines) standards. When used as text, it's crucial to ensure a contrast ratio of at least 4.5:1 against the background color for normal text and 3:1 for large text (14pt bold or 18pt regular). Using a lighter text color like white or a very light gray would generally be inappropriate. Darker backgrounds tend to offer the best contrast for this blue. Also, avoid using this color alone to convey critical information; always supplement it with text or other visual cues to accommodate users with color blindness. When using this color in interactive elements, such as buttons or links, ensure sufficient contrast for hover and focus states as well, to provide clear visual feedback for all users, including those navigating with keyboard.
