How hex and RGB color is used in CSS?

The most common way to specify colors in CSS is to use their hexadecimal (or hex) values. Hex values are actually just a different way to represent RGB values. Instead of using three numbers between 0 and 255, you use six hexadecimal numbers. Hex numbers can be 0-9 and A-F.

Can you use RGB in CSS?

The CSS rgb() function can be used to provide a color value when using CSS. It allows you to specify an RGB color value by specifying the red, green, and blue channels directly. The RGB value is provided as a comma-separated list of three values — providing the red, green, and blue hues respectively.

What is the maximum parameter value in RGB colors?

255
Each parameter (red, green, and blue) defines the intensity of the color with a value between 0 and 255. This means that there are 256 x 256 x 256 = 16777216 possible colors! For example, rgb(255, 0, 0) is displayed as red, because red is set to its highest value (255), and the other two (green and blue) are set to 0.

Why are colors in hexadecimal?

The reason to use hexadecimal numbers is it’s a human-friendly representation of values in binary code. The color values are defined in values between 00 and FF (instead of from 0 to 255 in RGB). Numbers are used when the value is 1-9. Letters are used when the value is higher than 9.
