description

less provides number of useful color functions to alter and manipulate colors in different ways. less supports some of the color definition functions as shown in the table below −

sr.no. function & description example
1

rgb

it creates color from red, green and blue values. it has following parameters −

  • red − it contains integer between 0 - 255 or percentage between 0 - 100%.

  • green − it contains integer between 0 - 255 or percentage between 0 - 100%.

  • blue − it contains integer between 0 - 255 or percentage between 0 - 100%.

 
rgb(220,20,60)

it converts color with rgb values as −

#dc143c
2

rgba

it determines color from red, green, blue and alpha values. it has the following parameters −

  • red − it contains integer between 0 - 255 or percentage between 0 - 100%.

  • green − it contains integer between 0 - 255 or percentage between 0 - 100%.

  • blue − it contains integer between 0 - 255 or percentage between 0 - 100%.

  • alpha − it contains number between 0 - 1 or percentage between 0 - 100%.

 
rgba(220,20,60, 0.5)

it converts color object with rgba values as −

rgba(220, 20, 60, 0.5)
3

argb

it defines hex representation of color in #aarrggbb format. it uses the following parameter −

  • color − it specifies color object.

 
argb(rgba(176,23,31,0.5))

it returns the argb color as −

#80b0171f
4

hsl

it generates the color from hue, saturation and lightness values. it has following parameters −

  • hue − it contains integer between 0 - 360 which represents degrees.

  • saturation − it contains number between 0 - 1 or percentage between 0 - 100%.

  • lightness − it contains number between 0 - 1 or percentage between 0 - 100%.

 
hsl(120,100%, 50%)

it returns the color object using hsl values as −

#00ff00
5

hsla

it generates the color from hue, saturation, lightness and alpha values. it has the following parameters −

  • hue − it contains integer between 0 - 360 which represents degrees.

  • saturation − it contains number between 0 - 1 or percentage between 0 - 100%.

  • lightness − it contains number between 0 - 1 or percentage between 0 - 100%.

  • alpha − it contains number between 0 - 1 or percentage between 0 - 100%.

 
hsla(0,100%,50%,0.5)

it specifies the color object using hsla values as −

rgba(255, 0, 0, 0.5);
6

hsv

it produces the color from hue, saturation and value values. it contains following parameters −

  • hue − it contains integer between 0 - 360 which represents degrees.

  • saturation − it contains number between 0 - 1 or percentage between 0 - 100%.

  • value − it contains number between 0 - 1 or percentage between 0 - 100%.

 
hsv(80,90%,70%)

it converts color object with hsv values as −

#7db312
7

hsva

it produces the color from hue, saturation, value and alpha values. it uses the following parameters −

  • hue − it contains integer between 0 - 360 which represents degrees.

  • saturation − it contains number between 0 - 1 or percentage between 0 - 100%.

  • value − it contains number between 0 - 1 or percentage between 0 - 100%.

  • alpha − it contains number between 0 - 1 or percentage between 0 - 100%.

 
hsva(80,90%,70%,0.6)

it specifies color object with hsva values as −

rgba(125, 179, 18, 0.6)
