RGB represents colors in CSS. There are three streams in this nomenclature representing a color, namely the Red, Green, and Blue streams. The intensity of colors is represented using numbers 0 to 255. This allows CSS to have a spectrum of visible colors.
These three colors can be in form of numbers (0 to 255) or percentages.
- RGB(255, 0, 0) or RGB(100%, 0, 0) is RED, as red is set to its highest value.
- RGB(0, 255, 0) or RGB(0, 100%, 0) is GREEN, as green is set to its highest value.
- RGB(0, 0, 255) or RGB(0, 0, 100%) is BLUE, as blue is set to its highest value.
Example 1:
HTML
<!DOCTYPE html> <html>
<head>
<style>
div {
width: 100px;
height: 100px;
border: 2px solid;
display: flex;
float: left;
margin: 10px;
border-radius: 10px;
}
.box1 {
/* rgb(100%, 0, 0) */
background-color: rgb(255, 0, 0);
}
.box2 {
/* rgb(0, 100%, 0) */
background-color: rgb(0, 255, 0);
}
.box3 {
/* rgb(0, 0, 100%) */
background-color: rgb(0, 0, 255);
}
</style>
</head>
<body>
<h2 style="color:green">GeeksforGeeks</h2>
<div class="box1"></div>

Example 2: We can use rgb() for different colors.

background-color: rgb(230, 77, 163);
}
.box3 {
background-color: rgb(106, 90, 205);
