CSS Colors

Colors are displayed combining RED, GREEN, and BLUE light.

---

Colors in CSS are most often specified by:

• a valid color name - like "red"
• an RGB value - like "rgb(255, 0, 0)"
• a HEX value - like "#ff0000"

Color Names

Colors set by using color names:

Example

Color	Name
	Red
	Green
	Blue
	Orange
	Yellow
	Cyan
	Black

Note: Color names are case-insensitive: "Red" is the same as "red" or "RED".

HTML and CSS supports 140 standard color names.

RGB (Red, Green, Blue)

RGB color values can be specified using this formula: rgb(red, green, blue).

Each parameter (red, green, blue) defines the intensity of the color between 0 and 255.

For example, rgb(255,0,0) is displayed as red, because red is set to its highest value (255) and the others are set to 0. Experiment by mixing the RGB values below:

Red	Green	Blue
255	12	0

rgb(255, 12, 0)

Example

Color	RGB
	rgb(255,0,0)
	rgb(0,255,0)
	rgb(0,0,255)
	rgb(255,165,0)
	rgb(255,255,0)
	rgb(0,255,255)
