HTML Color Values

HTML colors are defined using a hexadecimal notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex #00). The highest value is 255 (hex #FF).

Turn off the Red
If you turn off the Red light completely, there are 65536 different combination of Green and Blue (256×256) to experiment with. Click here to see some of these combinations of Green and Blue.

Turn on the Red
By setting the Red parameter to its maximum value, there are still 65536 different combination of Green and Blue (256×256) to experiment with. Click here to see some of these combinations of Green and Blue.

16 Million Different Colors
The combination of Red, Green and Blue values from 0 to 255 gives a total of more than 16 million different colors to play with (256×256×256). Most modern monitors are capable of displaying at least 16384 different colors. If you look at the color table below, you will see the result of varying the red light from 0 to 255, while keeping the green and blue light at zero. To see a full list of 16384 different colors based on red light varying from 0 to 255, click on one of the hexadecimal or rgb values below.
