HTML Colors

HTML colors are a mixture of red, green, and blue.

Color Values

HTML colors are defined by a hexadecimal notation, which is composed of Red, Green, and Blue values (RGB).

The minimum value of each color is 0 (hexadecimal: #00). The maximum value is 255 (hexadecimal: #FF).

This table shows the specific effects of the three colors mixed:

16 Million Different Colors

The combination of the three colors red, green, and blue ranges from 0 to 255, and there are 16 million different colors (256 x 256 x 256).

In the color table below you will see different results, red from 0 to 255, and set the value of green and blue to 0 at the same time. As the value of red changes, different values show different colors.

What are Web Safe Color?

A few years ago, when most computers only supported 256 colors, a series of 216 Web-safe colors were recommended as Web standards. The reason is that Microsoft and Mac operating systems use 40 different reserved fixed system colors (approximately 20 colors are used by each side).

We are not sure how meaningful this is now, because more and more computers are capable of processing millions of colors, but it is up to you to make the choice.

Initially, 216 cross-platform web-safe colors were used to ensure that when computers use a 256-color palette, all computers can display all colors correctly.
