0000FF

0000ff is a hexadecimal color code that represents the color pure blue in digital media and web design. The code consists of six hexadecimal digits, where "00" represents the red component, "00" represents the green component, and "ff" (which equals 255 in decimal) represents the blue component. This color code is part of the RGB (Red, Green, Blue) color model commonly used to define colors on computer screens, websites, and digital interfaces.

In RGB color notation, #0000ff corresponds to RGB(0, 0, 255), meaning it contains no red or green components but maximum blue intensity. This color is considered one of the primary colors in the additive color model used for digital displays. It is often referred to as "pure blue" or "web blue" and has been a standard color in web design since the early days of HTML.

The hexadecimal color system, which uses base-16 numbering (0-9 and A-F), allows for representation of 16,777,216 possible colors (256³). 0000ff has also been one of the 16 colors defined in the original VGA color palette for early computers and remains a widely recognized standard color in modern web design. CSS (Cascading Style Sheets) recognizes "0000ff" as a valid color declaration, and many programming languages support it for defining colors in user interfaces and graphics applications.
