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)
