General Information about Nile Blue
The hex color #223D4F, also referred to as Nile Blue, is a dark, muted shade of blue within the cyan-blue color family. It is composed of 13.3% red, 23.9% green, and 31% blue, represented in the RGB color space. In the CMYK color model, it consists of 57% cyan, 23% magenta, 0% yellow, and 69% black. This particular shade of blue conveys a sense of calmness, sophistication, and stability. Due to its relatively low saturation and dark tone, Nile Blue is often associated with professionalism and trustworthiness, making it a popular choice for corporate branding and design elements where these qualities are desired. Its subtle nature allows it to blend well with various other colors, offering versatility in design applications.
The color #223D4F, also known as Nile Blue, presents some accessibility challenges, particularly in text applications. Its relatively low luminance value of approximately 0.12 makes it difficult to provide sufficient contrast against lighter backgrounds, which is crucial for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #223D4F for text, ensure that it is paired with a very light background to meet these contrast requirements. Alternatively, consider using it for decorative elements or backgrounds where contrast is less critical. Careful consideration of font size and weight can also help improve legibility. When using this color for interactive elements like buttons, ensure that the contrast is sufficient in various states (hover, focus, active) to provide a clear visual cue to users.
