Color Names
In HTML, a color will be indicated using a color name:
Example
| Color | Name |
|---|---|
| Red | |
| Orange | |
| Yellow | |
| Cyan | |
| Blue |
HTML has the ability to support 140 standard color names.
Example
| Color | RGB |
|---|---|
| rgb(255,0,0) | |
| rgb(255,255,0) | |
| rgb(0,255,0) | |
| rgb(0,255,255) | |
| rgb(0,0,255) |
Shades of gray are usually mentioned by equal values with respect to all the 3 light sources:
Example
| Color | RGB |
|---|---|
| rgb(0,0,0) | |
| rgb(90,90,90) | |
| rgb(128,128,128) | |
| rgb(200,200,200) | |
| rgb(255,255,255) |

In HTML, a color can also be mentioned by a hexadecimal value in the form: #RRGGBB, where RR (red), GG (green) and BB (blue) are found to be hexadecimal values between 00 and FF (same as decimal 0-255).
For example, #FF0000 is being shown as red, as red is set to have its highest value (FF) and the others are set to have the lowest value (00).
