It evokes imagery of the ocean and sky, making it a popular choice for designs aiming to create a sense of peace and tranquility. Its versatility allows it to be utilized in a variety of applications, from web design to fashion, each leveraging its unique psychological impact.

The hex color #1C4ACA, also known as Cerulean Blue, presents some accessibility challenges, particularly when used as a background or text color. Its relatively low luminance contrast against both white and black backgrounds requires careful consideration. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. For text, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. When using #1C4ACA for text, pair it with very light colors like white (#FFFFFF) or very dark colors like black (#000000) to achieve adequate contrast. Tools like contrast checkers can help assess compliance. If used as a background, ensure foreground elements provide sufficient contrast. Additionally, avoid relying solely on color to convey information, as colorblind users may struggle to distinguish it. Using supplementary cues like text labels or icons will improve usability for all users.
