CSS - Colors

CSS uses Hexadecimal or Numerical values to specify a color. These are used to set the color of the background or foreground of an element(i.e., its text). It can also be used to impart  color to the borders and other decorative effects.

Colors in CSS can be specified in various formats. Following table tells you all possible formats:

Format	Syntax	Example
Hex Code	#RRGGBB	p {color:#FF0000;}
Short Hex Code	#RGB	p {color:#6A7;}
RGB %	rgb(rrr%,ggg%,bbb%)	p{color:rgb(50%,50%,50%);}
RGB Absolute	rgb(rrr,ggg,bbb)	p {color:rgb(0,0,255);}
keyword	aqua, black, etc.	p {color:teal;}

These formats are explained in more detail in the following sections:

CSS Colors - Hex Codes:

A hexadecimal is a 6 digit representation of a color.
first two digits(RR) represent a red valu.

last  two digits(BB) represent a blue value.
A hexadecimal value can be taken from any graphics software like Adobe Photoshop, Jasc Paintshop Pro or even using Advanced Paint Brush.
Each hexadecimal code will be preceded by a hash sign #.

A hexadecimal value can be taken from any graphics software like Adobe Photoshop, Jasc Paintshop Pro or even using Advanced Paint Brush.

CSS Colors - RGB Values:

This color value is specified using the rgb( ) property. This property takes three values, one each for red, green, and blue. The value can be an integer between 0 and 255 or a percentage.

NOTE: All the browsers does not support rgb() property of color so it is recommended not to use it.
