CSS and HTML Color Names and Codes - Learn How to Use Them Effectively

CSS is used to style HTML tags. It is important to learn HTML before starting CSS. If you have learned html then let's start otherwise you can learn html from here.

First think about how we get color. If you know even a little bit about chemistry, you know that all colors are products of three colors which are red, green and blue. So the basic formula to get color is rgb. RGB stands for red, green and blue. We take each color value from 0 to 256 as rgb(115, 225, 230) which returns a new color.

But this is not the only way to achieve the final colors. Colors can also be derived from color names and color codes. Color names are defaults such as white, yellow, red or black which are supported by almost all browsers. There are about 140 predefined color names in CSS. There are different formats of color codes like Hexadecimal, Hexadecimal with transparency, RGB, RGBA, HSL, HSLA etc.

A hexadecimal color is specified with: #RRGGBB, where RR (red), GG (green) and BB (blue) are hexadecimal integers describing the color components. All values ​​must be between 00 and FF.

For example, the value #0000ff is rendered as blue, because the blue component is set to its highest value (ff) and the others are set to 00.

Example

Define different HEX colors:

#p1 {background-color: #ff0000;} /* red */

#p2 {background-color: #00ff00;} /* green */

#p3 {background-color: #0000ff;} /* blue */

A hexadecimal color is specified with: #RRGGBB. To add transparency, add two extra digits between 00 and FF.

Example

Define different HEX colors with transparency:

#p1a {background-color: #ff000080;} /* red transparency */

#p2a {background-color: #00ff0080;} /* green transparency */

#p3a {background-color: #0000ff80;} /* blue transparency */

An RGB color value is specified with the rgb() function, which has the following syntax:

RGB (Red, Green, Blue)

Each parameter (red, green and blue) defines the intensity of the color and can be a number between 0 and 255 or a percentage value (from 0% to 100%).

For example, the rgb(0,0,255) value is rendered as blue, because the blue parameter is set to its highest value (255) and the others are set to 0. .

Also, the following values ​​define equal color: rgb(0,0,255) and rgb(0%,0%,100%).

Example

Define different RGB colors:

#p1 {background-color: rgb(255, 0, 0);} /* red */

#p2 {background-color: rgb(0, 255, 0);} /* green */

#p3 {background-color: rgb(0, 0, 255);} /* blue */

RGBA color values ​​are extensions of RGB color values ​​with an alpha channel - which defines the opacity of the object.

An RGBA color is specified with the rgba() function, which has the following syntax:

rgba (red, green, blue, alpha)

The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).

Example

Define different RGB colors with opacity:

#p1 {background-color: rgba(255, 0, 0, 0.3);} /* red with opacity */

#p2 {background-color: rgba(0, 255, 0, 0.3);} /* green with opacity */

#p3 {background-color: rgba(0, 0, 255, 0.3);} /* blue with opacity */

HSL stands for hue, saturation, and lightness - and is a cylindrical coordinate representation of colors.

An HSL color value is defined with the hsl() function, which has the following syntax:

hsl (hue, saturation, lightness)

There is a degree on the color wheel (from 0 to 360) - 0 (or 360) is red, 120 is green, 240 is blue. Saturation is a percentage value; 0% means shade of gray and 100% is full color. Lightness is also one percent. 0% is black, 100% is white.

Example

Explain the different HSL colors:

#p1 {background-color: hsl(120, 100%, 50%);} /* green */

#p2 {background-color: hsl(120, 100%, 75%);} /* light green */

#p3 {background-color: hsl(120, 100%, 25%);} /* dark green */

#p4 {background-color: hsl(120, 60%, 70%);} /* pastel green */

HSLA color values ​​are extensions of HSL color values ​​with an alpha channel - which defines the opacity of the object.

An HSLA color value is defined with the hsla() function, which has the following syntax:

hsla (hue, saturation, lightness, alpha)

The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).

Example

Define different HSL colors with opacity:

#p1 {background-color: hsla(120, 100%, 50%, 0.3);} /* green with opacity */

#p2 {background-color: hsla(120, 100%, 75%, 0.3);} /* light green with opacity */

#p3 {background-color: hsla(120, 100%, 25%, 0.3);} /* dark green with opacity */

#p4 {background-color: hsla(120, 60%, 70%, 0.3);} /* pastel green with opacity */
