General Information about #284CBE

The hex color #284CBE, commonly known as cerulean blue, is a vibrant and saturated shade of blue. It sits within the blue color spectrum and is often associated with tranquility, depth, and stability. In color theory, cerulean blue is created by mixing blue and cyan pigments, resulting in a slightly greenish-blue hue. Hexadecimal color codes, like #284CBE, are used in web design and digital media to precisely define colors. Understanding the properties of #284CBE, such as its RGB (red, green, blue) values and its HSL (hue, saturation, lightness) values, allows designers and developers to manipulate and integrate it effectively into various projects. It is a versatile color, suitable for both light and dark themes depending on the surrounding colors.

The hex color #284CBE, a shade of cerulean blue, presents some accessibility challenges. With a relatively low luminance, using this color as a background for light text can create insufficient contrast, making it difficult for users with visual impairments to read. Therefore, it's recommended to use a very light color such as #FFFFFF or #F0F0F0 for text on a #284CBE background. Conversely, dark text on a #284CBE background may also lack sufficient contrast. Tools such as WebAIM's contrast checker are invaluable for ensuring sufficient contrast ratios, ideally aiming for WCAG AA or AAA compliance. When using #284CBE, consider the color blindness of the target audience and test for protanopia, deuteranopia and tritanopia to ensure content remains accessible to all users. Always provide alternative ways for users to access content, such as using icons or text labels in addition to color.
