Color Values
HTML colors are defined using a hexadecimal notation (HEX) 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 (in HEX: 00). The highest value is 255 (in HEX: FF).
HEX values are specified as 3 pairs of two-digit numbers, starting with a # sign.
16 Million Different Colors
The combination of Red, Green, and Blue values from 0 to 255, gives more than
16 million different colors (256 x 256 x 256).
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 the full list of color mixes when RED varies from 0 to 255, click on one of the HEX or RGB values below.
Shades of Gray
Gray colors are created by using an equal amount of power to all of the light sources.
To make it easier for you to select the correct shade, we have created a table of gray shades for you:
Web Safe Colors?
Some years ago, when computers supported max 256 different colors, a list of 216 “Web Safe Colors”
was suggested as a Web standard, reserving 40 fixed system colors.
The 216 cross-browser color palette was created to ensure that all computers would display the colors correctly
when running a 256 color palette.
This is not important today, since most computers can display millions of different colors. Anyway, here is the list:
