Blue may refer to any of the following:
1. Blue is a color that resembles the day sky. For example, this text is blue. As an HTML (hypertext markup language) color code, blue is represented as #0000FF or #00F in CSS (cascading style sheets) shorthand, which is hexadecimal for 0 red, 0 green, and 255 blue. The image shows an example of the blue color code with the RGB (red, green, and blue), HSL (hue, saturation, and lightness), and that it's a web safe color.
Tip
If a link color is not defined, a browser defaults the color to blue.
2. With color-coded ports, blue is the color used to identify the VGA (video graphics array) port for a VGA cable connected to a monitor. See our color-coded page for further information and other color-coded colors.
