-HTML Colors

Colors are displayed combining RED, GREEN, and BLUE light sources.
Color Values
HTML colors can be defined as a hexadecimal notation for the combination of Red, Green, and Blue color values (RGB).
The lowest value that can be given to one light source is 0 (hex #00) and the highest value is 255 (hex #FF).
The table below shows the result of combining Red, Green, and Blue light sources:.

Cross-browser Color Values
Some years ago, when most computers only supported 256 different colors, a list of 216 Web Safe Colors was suggested as a Web standard. The reason for this was that the Microsoft and Mac operating system used 40 different "reserved" fixed system colors (about 20 each).
We are not sure how important this is now, since most computers today have the ability to display millions of different colors, but the choice is left to you.
The 216 cross-browser color palette was created to ensure that all computers would display the colors correctly when running a 256 color palette:
