HTML/CSS Colors

How to specify colors using color name, hexadecimal (hex) value
or rgb(), rgba(), hsl(), hsla() functional notation.

HTML/CSS Color Values

In HTML/CSS colors could be specified in multiple ways:

 

  Color name - Sample: "black"

  RGB (Red-green-blue) hexadecimal (hex) value - Sample: "#000000"

  RGB (Red-green-blue) functional notation - Sample: "rgb(0,0,0)"

  RGBA (Red-green-blue-alpha) functional notation - Sample: "rgb(0,0,0,1.0)"

  HSL (Hue-saturation-lightness) functional notation - Sample: "hsl(0,0%,0%)"

  HSLA (Hue-saturation-lightness-alpha) functional notation - Sample: "hsla(0,0%,0%,1.0)"

 

 

Color Names

A color name is a keyword representing a specific color, for example: cadetblue.
Color names are case-insensitive, which means "black" equals "Black".

 

Samples:

HTML: <div style="color:black;">

CSS: .classname {color:black;}

Red-Green-Blue (RGB) Hexadecimal (hex) Value

Color as hexadecimal value in the format #RRGGBB.
R=red, G=green, b=blue hexadecimal value between 0 and FF (equals decimal 255)

 

Samples:

HTML: <div style="color:#efef00;">

CSS: .classname {color:#efef00;}

 

#000000
(black)
#FF0000
(red)
#00FF00
(green)
#0000FF
(blue)

 

The hex value can be shortened to #RGB, e.g. #F00 = #FF0000.

 

Red-Green-Blue rgb() Functional Notation

Color as decimal value in the form: rgb(R,G,B)
R=red, G=green, b=blue decimal value between 0 and 255 (equals hex FF)

 

Samples:

HTML: <div style="color:rgb(128,128,64);">

CSS: .classname {color:rgb(128,128,64);}

 

rgb(0,0,0)
(black)
rgb(255,0,0)
(red)
rgb(0,255,0)
(green)
rgb(0,0,255)
(blue)

Red-Green-Blue-Alpha rgba() Functional Notation

Color as decimal value in the form: rgba(R,G,B,A)
R=red, G=green, b=blue decimal value between 0 and 255 (equals hex FF)
A=alpha (transparency) value between 0.0 (fully-transparent/invisible) and 1.0 (non-transparent)

 

Samples:

HTML: <div style="color:rgba(128,128,64,1.0);">

CSS: .classname {color:rgba(128,128,64,1.0);}

 

rgba(0,0,0,1.0)
(black 100%)
rgba(255,0,0,1.0)
(red 100%)
rgba(0,255,0,1.0)
(green 100%)
rgba(0,0,255,1.0)
(blue 100%)

 

 

Alpha Sample: Blue on a white background

 

rgba(0,0,255,1.0)

Hue-Saturation-Lightness hsl() Functional Notation

The hsl model uses the rainbow color circle (hue) combined with color saturation and lightness in the format: hsl(H,S,L)
H (Hue) = Angle of the color circle from 0 to 360
S (Saturation) = Color saturation from 0% to 100% (100% is full saturation, 0% is a shade of grey)
L (Lightness) = Lightness from 0% to 100% (50% is normal, 100% is white, 0% is black)

 

Samples:

HTML: <div style="color:hsl(240,100%,50%);">

CSS: .classname {color:hsl(240,100%,50%);}

 

hsl(0,0%,0%)
